Vi segnato questo nuovo programma che credo possa essere molto utile!
E' un sistema decentralizzato per invio/ricezione di messaggi.
I messaggi viaggiano sui nodi connessi al network (su un database condiviso fra tutti loro, un pò come il blockchain di Bitcoin), ma sono naturalmente criptati, e sono leggibili solo dai proprietari delle varie chiavi private. (che risiedono localmente)
Questo vuol dire che è un ottima alternativa all'email e non si è dipendenti da nessun servizio terzo.
Non è quindi nemmeno richiesto che 2 persone siano per forza connesse contemporaneamente per poter scambiarsi messaggi, possono inviare e ricevere ad orari/giorni diversi.

Il sistema funziona anche bene facendolo passare attraverso sistemi di proxy come Tor. (impostate come ip: 127.0.0.1)

Servizio per poter ricevere/inviare messaggi sul client via email:
https://bitmessage.ch/
Secure, Anonymous "Twitter" w. Bitmessage
https://bitchirp.org
Bitmessage PHP class
https://bitmessage.org/forum/index.php?topic=3657.0

Transactions must be included in a block to be properly completed. When you send a transaction, it is broadcast to miners. Miners can then optionally include it in their next blocks. Miners will be more inclined to include your transaction if it has a higher transaction fee.

E' una rete alternativa, fuori dal sistema email.
Il vantaggio di questo sistema, è che puoi accederci sempre, non devi collegarti ad un server in particolare.
Ti colleghi al network e ricevi/invii i messaggi.

Ho cercato ma non trovo info, sarà che c'ho anche sonno: si potranno creare indirizzi umanamente leggibili?
Comunque altra bellissima novità, da provare appena possibile. Prima viene la salute.
Avevo cercato in passato se esistevano progetti di email decentralizzata, ho trovato questo http://www.epostmail.org/ ha qualcosa in comune?

Per ora no, ma si sta pensando a qualche soluzione, non è detto però che arriverà nel prossimo futuro.

No, è un alternativa all'email. E' un sistema di messaggistica a se stante. Protocollo diverso.

1. tutto quello che bisogna backuppare è solo la keys.dat ?
2. c'è un modo per cambiare il percorso della keys.dat ?

Si, ma farlo anche di messages.dat sarebbe una cosa in più (per salvarsi magari anche la lista dei propri che si è già letti)

2. c'è un modo per cambiare il percorso della keys.dat ?
Per ora mi pare di no, ma se attivi l'opzione "portable", i dati li prenderà dai file presenti nella stessa cartella dell'eseguibile.

Ti saprà sicuramente spiegare meglio Hostfat, ma:
1.Personalmente sto studiando la cosa solo da questo pomeriggio (e mi sono pure appisolato), per ora ho deciso di fare il backup della cartella .PyBitmessage con tutto il contenuto, tanto è poca roba. A quanto ho capito dalle istruzioni sul sito, sì, sarebbe sufficiente solo keys.dat che dovrebbe contenere sia le chiavi che le eventuali etichette.
Se crei solo indirizzi deterministici, invece, basterebbe ricordarsi unicamente la passphrase più un paio di numeri, senza alcun bisogno di backup "fisico".
2.in settings c'è l'opzione "run in portable mode" con sotto anche la spiegazione di come funziona. Non ho ancora provato perchè sto cercando una chiavetta o schedina SD su cui installarlo.

Si, sul database nel network (presente sui vari nodi, come il blockchain di Bitcoin) sono già indicati come ricevuti, e quindi probabilmente gli altri nodi lo cancellano dal loro database locale.
Dovresti ancora avere message.dat nella vecchia cartella dati, quindi se gli ripassi quelli dovresti recuperare tutto.

recuperato il vecchio message.dat con il messaggio che ti ho inviato (lo hai ricevuto?)

era meglio se i messaggi rimanevano nel network.

Se è un altro, devo ancora finire di scaricare i messaggi, appena avviato ...

Può essere che il dev dia possibilità di cambiare questa cosa in futuro.

Ma può anche essere che sia una scelta di sicurezza.
Una volta letto il messaggio, forse è meglio che nessun'altro sia in grado. (es: entrando in possesso delle tue chiavi)

humm... pro e contro, se uso la stessa chiave su 2 pc non posso "fondere" i message.dat

L'interfaccia lascia ancora un po' a desiderare, ho cliccato col tasto destro su un messaggio, scappato il dito... sparito il messaggio, si era autoselezionata la voce "move to trash". E non mi pare ci sia modo di recuperarlo, giusto?

Va bè, per ora penso di dover rinunciarci, peccato.
Funziona solo al primo avvio (ho anche inviato/ricevuto un paio di messaggi) ma al secondo non c'è più attività, nonostante abbia 8 connessioni. Se lo reinstallo da zero, cancellando anche tutto il contenuto di .PyBitmessage funziona per quella sessione e poi basta. Sob! Cry

Ora lo dici?  Grin
Quindi non rimane che aspettare o installare la versione precedente... se si trova.

Ho risposto, e mi risultava messaggio ricevuto, tsè. Se vuoi ti mando lo screenshot.  Grin
Nel dubbio avevo mandato anche un PM qui.

In ogni caso non funziona, pare non basti reinstallare PyBitmessage da capo, bisogna cancellare completamente la cartella .PyBitmessage. Anche lasciare uno solo dei file creati durante la prima sessione (keys.dat o messages.dat) pare bloccarne il funzionamento.
Boh, Chi ci capisce qualcosa? Possibile non capiti al developer?

Bitmessage v0.3.0 is available. It is an important release with a new change relevant to everyone.
The most significant change is the move from version 2 to version 3 addresses.
With version 3 addresses, users may set the minimum-Proof-of-Work-difficulty that they require of others in order to receive a message. The network-minimum difficulty is 1 but you may, for example, demand that people who send you messages accomplish a proof of work with a difficulty of 1.5.
Before making new addresses, see the 'Demanded difficulty' tab in the settings menu.
The next new feature is encrypted broadcasts. Broadcasts sent from v3 addresses will now all be encrypted. Broadcasts sent from v2 addresses will remain in clear-text until 2013-05-28 at 10:00 UTC at which time all upgraded clients will automatically switch to using encrypted broadcasts for all addresses.
Note that broadcasts are only encrypted with the address of the person sending them.
Anyone who has the address may read the broadcast. Some people may try to decrypt all broadcasts with all addresses ever seen on the network; this is expected.
The purpose of this feature is to encrypt the data sufficiently well such that unencrypted data will not flow through your Internet connection that you are not actually interested in.
Going forward, all new addresses will be v3 addresses thus it would be wise to upgrade soon so that you may receive messages from new Bitmessage users. v2 and v3 addresses will remain mutually-compatible indefinitely.
The next new feature is Daemon mode which allows Bitmessage to run without a graphical user interface. https://bitmessage.org/wiki/Daemon
You may report issues to the Github issue tracker or by replying to this bitmessage. https://github.com/Bitmessage/PyBitmessage/issues
Users who downloaded the source code with git may use 'git pull origin master' to upgrade.
All the best, Atheros

E' uscita la 0.3.4, anche se non è ancora presente il changelog.

Si sono aggiunti tanti altri sviluppatori, ed è probabile che fra non molto avremo un light client android, che si connetterà a server remoti (magari quello installato a casa o altrove...) per eseguire il PoW, e poter poi inviare il messaggio al network Smiley

Al che si avrà un sistema di messaggistica, completamente decentralizzato, sicuro e a portata di mano ovunque!

Questo servizio permette di usare il network di Bitmessage senza installare niente, direttamente da browser.
Attualmente il PoW viene eseguito serverside, ma è probabile che venga presto portato su javascript.
Naturalmente c'è un calo di sicurezza facendo uso di un servizio simile Wink

Uno sviluppatore si sta preparando a creare già un alternativa a Bitmessage! Partendo da zero.

Bitmask: A Perfectly Anonymous, Naturally Scalable Peer-to-Peer Messaging System

Tommy Anderson
tommy a@mit.edu
www.bitmask.me

v0.1.0 - September 6, 2013

Abstract. We propose a trustless peer-to-peer messaging system that allows peers to securely send and receive anonymous, plausibly deniable messages, without exposing one’s true identity. Through the combined defensive efforts of a minimum spanning tree of non- malicious peers, the system is shown to be resilient to attempts made by malicious peers to disrupt both the activity and anonymity of the system. Additionally, peers are responsible for self-regulating and maintaining the health of the system, in a way that is both scalable and fair to all peers.

1 Introduction
Peer-to-peer (P2P) messaging as it currently exists lacks a proper trustless solution that is both anonymous and scalable. A system known as Bitmessage attempts to be such a solution, however its approach to anonymizing the identity and activities of peers prevents the system from achieving the scalability needed for mainstream adoption. This section will analyze the shortcomings of Bitmessage, as well as introduce a new solution titled Bitmask.

1.1 Bitmessage
The private information retrieval (PIR) approach that Bitmessage takes to anonymize the activities of peers is to have each peer download and forward every message within the system’s network. This is done to obfuscate both the addresses that belong to the peer and those that the peer is in communication with. Bandwidth limitations render such a system impractical for use on a mobile device. More generally speaking, usage is limited strictly to those who are willing to store and transfer large amounts of data over a given period of time.

Bitmessage attempts to scale by allowing peers to split up into separate bandwidth partitions of the network known as streams. Streams however limit a peer’s anonymity to a function of how many peers are in a specific stream, rather than the entire network.

Additionally, it has been shown that various timing attacks exist that can be used to break anonymity. These timing attacks result from the exploitation of Bitmessage network protocol packets known as acknowledgment messages. Lack of link layer encryption also makes it possible for anonymity to be broken by internet service providers (ISPs).

1.2 Bitmask
To remedy these shortcomings and provide a system that is both scalable and anonymous, a new system titled Bitmask is proposed with the following features. These feature descriptions give a high level overview of the system, and will be explained in greater detail within the sections to follow.

Note: symmetric-key encryption, the usage of public and private keys to sign and encrypt messages, is used in a manner similar to Bitmessage, including the concept of addresses to shorten public keys.

1.2.1 Perfect Forward Secrecy
Instead of always sending encrypted messages to the same address for a particular contact, a peer will generate a new public/private key pair before sending a new message, and include the new public key at the end of the message. The one-time address associated with this public key is known as an ephemeral address; an address to be used more than once is known as non-ephemeral. When the recipient reads this message, it will know which new ephemeral address the sender is listening on for a reply, and send a reply accordingly. If the most recent private key for one of the two peers communicating is ever compromised, all previous messages in the conversation are safe as long as the previous private keys were discarded, thus achieving perfect forward secrecy.

1.2.2 Plausible Deniability
By including one’s ephemeral private key at the end of every encrypted message and then discarding that private key, one can deny having written a message if accused outside of the network by the recipient. This is because the recipient had the means to forge the message by possessing the private key at the end. Because all peers never use the same address twice, there is no need for identity-theft concern when releasing the private key, as there is no identity to protect.

1.2.3 Link Layer Encryption
By using transport layer security (TLS) to communicate with and send packets over the network to peers, link layer encryption will be provided, and ISPs will be unable to read the contents of packets.

1.2.4 Advertisement Packets
To preserve the anonymity that comes with Bitmessage’s PIR scheme of everyone gets every- thing without actually forwarding and receiving every message, advertisement (ad) packets are used. All messages are advertised to the network as a special ad packet before ever being transferred between peers. This ad packet contains the recipient address of the message being advertised, as well as the time of expiration for how long the peer passing along this ad is willing to respond to requests from other peers to send them the message.

1.2.5 Randomized Caching
Instead of using streams and Bitmessage’s PIR scheme of everyone gets everything, Bitmask uses a concept called random caching. After learning from ad packets what messages are available to download from peers, a peer will randomly and regularly ask to download cer- tain messages from certain peers. The peer will then cache these messages for an agreed upon amount of time, and transfer them to other peers if requested. The peer’s activity is obfuscated by the fact that no peer can tell which messages are of interest to the peer, and the fact that messages sent by the peer are introduced into the network as an ad whose origin of broadcast is undetermined.

1.2.6 Bandwidth for Anti-Flood
Bandwidth metrics are used for protecting the network against flood attacks, instead of Bitmessage’s CPU based proof of work (POW). Natural bounds on system growth are de- fined by self-verifiable and trustless rules between peers, such as bandwidth agreements and statistically allowable thresholds for message transfer and dropping. Malicious peers must follow these rules or risk being dropped by the non-malicious peers who have set them. As a result, malicious peers can only flood in proportion to how much network traffic they are facilitating, which in effect helps the network by adding additional noise.

1.2.7 Permission Packets
In order to prevent spam, all ad packets for messages contain the recipient address instead of the public key. Thus, special permission packets are needed to obtain a public key for non-ephemeral addresses shared outside of the network, in order to initiate a conversation and start sharing ephemeral public keys. Such a permission packet includes the recipient’s address as well as an ephemeral public key for the sender. The recipient can then reply to that public key with its own ephemeral address as an encrypted message (signed by the address requested in the permission packet in order to prevent false/spammed replys), thus allowing the permission requester to then send its first message.

1.2.8 Trustless Identity
In order to prevent attempts to spam permission packets by altering an original packet and rebroadcasting it with a new ephemeral public key, the first message that gets sent after permission has been granted must be a special identity profile message. The peer who is responding to the request can then read and subsequently decide whether or not to initiate a conversation with whoever the sender claims to be (ie: take an accept or reject type of action).

Note: this identity is a claim, it doesn’t guarantee the peer is who he says he is

1.2.9 Low-Bandwidth Accessibility
Peers such as those on mobile phones can request to only receive ad packets that advertise the availability of messages being sent to a specified range of addresses. As long as these peers provide some constant amount of bandwidth to frequently send and receive messages, anonymity is preserved.

2 P2P Systems
P2P based systems like Bitmask and Bitmessage are made up of a decentralized and dis- tributed network of peers. Such peers take on both the role of consumer and producer, each providing some portion of individual resources to the network. Bitmask is designed to be a trustless P2P system, in which network protocol never dictates the trusting of peers to achieve proper functionality. For example, making the assumption that peers are caching all messages transferred to them without some form of verification or accountability would fail to result in a network that is trustless.

2.1 Minimum Spanning Tree of Trust
The only assumption that Bitmask makes with regards to the trusting of peers, is the as- sumption that a minimum spanning tree of non-malicious peers is present within the network. In other words, each peer must be connected to at least one non-malicious peer. If a peer sends messages out over time and never receives a response, he is only connected to mali- cious peers and the assumption is broken. As such, we can philosophically guarantee the validity of this assumption in the sense that the system is only useful if peers can use it to communicate with each other. Thus, as long as peers find Bitmask to be useful, the trustless nature of the system is preserved.

This assumption in combination with various methods of verification will be used to detect the presence of malicious peers within the network, as described in the sections to follow. Non-malicious peers will work together to set mutually-beneficial terms, but at the same time constantly verify the actions of each other in a trustless manner, in order to maintain the functionality of the network.

3 System Components
Central to the use of Bitmask is the usage of addresses for initiating and carrying out communication, in addition to two types of network packets; global packets for broadcasting to every peer within the network, and local packets for cooperating with specific peers.

3.1 Addresses
All addresses are of a form similar to the base 58 encoded addresses used by Bitmessage and the crypto-currency Bitcoin, in order to compress a peer’s public key and make it more user- friendly with regards to copying and pasting. Additionally, addresses help prevent spam by hashing the associated public key and preventing network observers from being able to scrape an ad packet and send an encrypted spam message to that public key. The checksum length is chosen to be the same as for Bitmessage. As a side-note, the shorter this checksum is, the greater the probability that collisions are possible when getting a response to a permission packet (ie: getting two responses back that are signed by different public keys that hash to the same address, which can be interpreted as two public keys claiming responsibility for the same permission packet).

3.2 Global Packets
The following types of packets are relayed from peer to peer until they’ve traversed the entire network.

3.2.1 Permission Request
This packet is needed for getting the public key of a non-ephemeral address and for subse- quently starting a conversation, as previously described.

3.2.2 Advertisement
This packet is needed to introduce the availability of a message within the network. When relaying this packet to another peer, both peers must agree on a time of expiration for how long the receiving peer is willing to answer requests from other peers to transfer the message being advertised. Determination of this time will be discussed in the section to come on network behavior.

3.2.3 Message
This packet contains encrypted content, such as an acknowledgment for receiving a previous message, a trustless identity profile message following a successful permission request, or a plain text message. It is sent when a peer requests it from another peer, sometime between the moment the receiving peer learns of the message’s presence from an advertisement packet, and the time of expiration for that advertisement.

3.3 Local Packets
The following types of packets are used for communication between two peers.

3.3.1 Bandwidth Agreement
Upon establishing a connection, two peers use this packet to enter into an agreement to provide an amount of message storage space for each other. The peer that offers the lower of the two amounts determines the amount agreed to.

3.3.2 Message Request
A vector of messages are requested in each packet of this type, based on which messages are available for request from the peer in question. Included in this request is the proposed time of storage for each message that a peer is requesting, so that the peer sending the files knows the duration of time that he has to spend verifying that the peer is caching the messages as promised. The sending peer will then begin to transfer the requested messages, either immediately if it currently has a message cached, or with a delay if the peer needs to request a message from one of its peers.

To determine how much time a peer will offer to store a message from another peer, a function with an input of the current amount of unused bandwidth minus the size of the file in question will be used (ie: how much space will remain after caching this message). This function will be exponential, where the smaller the amount of currently available space there is, the shorter a peer will be willing to hold on to messages. This curve will be adjusted depending on network activity, for example making it steeper in the presence of high traffic.

3.3.3 Checkup
Upon establishing a connection, two peers use this packet to enter into an agreement to checkup on each other over a regular interval of time, in order to verify that both peers are holding messages for as long as they promised to. In order to prove that caching is occurring, a random nonce is sent by one peer to the other. The receiving peer then computes and returns a checksum for each file plus this nonce, to prove that each file is currently stored.

Failure to respond within an adequate amount of time or to provide the correct answer results in the blacklisting of that peer. Each checkup packet will contain a list of files that in combination have a large total file size, to guarantee that the peer isn’t simply re-downloading the files from other peers.

3.3.4 Message Query
This packet is used to check if a peer is currently storing any messages for specific addresses, and if so, to transfer them. It sacrifices anonymity, but is useful for querying peers that are serving as storage services by keeping messages cached after their ads expires, for an addi- tional amount of time. Anonymity can be preserved by querying a large range of addresses. This packet should only be used by peers who have been offline and are reconnecting to the network.

4 Network Behavior
The following is an overview of interactions between peers.

4.1 Reciprocal Bandwidth
Because of the minimum spanning tree assumption, a peer must continually relay all ad packets within the network or risk being classified as a malicious peer, because all ads will eventually make their way through the minimum spanning tree to the recipient peer. So if a peer receives an ad for a message that it’s the recipient of but never receives the same ad from peers attempting to drop ad packets, those malicious peers can be detected and blacklisted.

Therefore peers must use their bandwidth for the good of the network, in addition to any “junk” (ie: messages to addresses not owned by any peer) they might want to introduce. The more bandwidth that a peer agrees to, the greater the chance that other peers will randomly cache files that the peer is attempting to send, because these peers will be requesting messages faster. Additionally, the more that peers cache messages, the quicker those messages will get to the intended recipient; it’s to every peer’s benefit to create a strong network pipeline.

If a peer is offline when a message is sent, that peer must attempt to query the message from a storage peer. Otherwise, the only other way to retrieve the message is to wait for the sender to either to resend the message, or to send a new permission packet to restart the conversation on a new ephemeral address.

4.2 Reciprocal Advertising
Peers must agree every so often on a constant time to advertise each others ads, because any messages a peer would try to send will then be reciprocally advertised for an equal amount of time. When a peer advertises a message to another peer, the recieving peer agrees to an expiration time no greater than the time of expiration the advertising peer previously agreed to for the same ad, and no more than the constant time they’re currently in agreement on. Thus, the longer a peer is willing to advertise messages, the longer its messages can be advertised within the network.

If a peer frequently fails to obtain and/or send a message after having been requested to do so, that peer can be blacklisted. The fact that a peer may no longer have access to a file due to advertisement expirations or disconnects in its path to obtain the file will be taken into account when determining such a threshold for blacklisting.

5 Anonymity
The following are various thoughts regarding the anonymity of Bitmask.

• Random caching based PIR and ephemeral addresses keeps interests masked; peers appear to simply be facilitating traffic
• By waiting a random amount of time before responding to permission requests, peers will be unable to detect if a non-ephemeral address belongs to a certain peer
• Unless completely connected to malicious peers (which would violate the minimum spanning tree assumption), no peer can prove the origin of an ad
• Because every message has a mutually agreed upon time of expiration based on ads, messages that are cached will be deleted upon expiration so that peers can’t abuse query requests to see if another peer is holding messages longer than they should be, thus giving away that the peer has interest in it (either sent or read it); deletion can be turned off if serving as a storage peer
• Link layer encryption protects against ISP’s from figuring out which ads originate from certain peers
• Message size increments and padding are not needed due to regular bandwidth fre- quency (ie: constantly pushing and pulling a set amount of data)

6 Spam
Public keys are never directly broadcasted within the network, so no peer can encrypt and send spam messages. The only possibility for spam is with regards to permission packets. Having a trustless identity profile message be the first message after permission has been granted gives a peer the means to accept or reject starting a conversation with the requesting peer. The more fields this profile has, the harder it will be for spam peers to generate a meaningful profile that a Bitmask client can choose to mark as spam, and flat out reject the conversation. A client can also allow users to whitelist certain addresses, and ignore permission requests signed by any other addresses.

7 Flooding
Because of the minimum spanning tree assumption, malicious peers must facilitate all normal traffic or risk being caught dropping messages, and blacklisted as a result. Thus a malicious node must support the current network, in addition to any packets it wishes to introduce. As a result of all peers establishing bandwidth requirements amongst themselves, they naturally limit how much data a malicious peer can push into the network, which in the end will only help peers gain more anonymity from each other. Additionally, peers will agree amongst themselves to have bandwidth caps for ad and permission packets to protect against network flood.

Domandina tecnica.
Formattato il mio pc e prima di farlo ho copiato la cartella C:\Users\miouser\AppData\Roaming\PyBitmessage
Ora ho reinstallato Bitmessage e sostituito i file della cartella con i vecchi. E' la soluzione corretta per ripristinare il mio indirizzo "vecchio".
Dico questo perchè ora il debug mi dice:
Code:
2013-11-13 13:38:36,736 - CRITICAL - Major error occurred when trying to execute a SQL statement within the sqlThread. Please tell Atheros about this error message or post it in the forum! Error occurred while trying to execute statement: "DELETE FROM inventory WHERE (receivedtime<?

Here is the actual error message thrown by the sqlThread: database disk image is malformed

Cancella la cartella, rilancia bitmessage, aspetta qualche secondo poi richiudi.
Entri nella cartella che è stata ri-creata e sostituisci solo il file messages.dat


Dovrebbe andare ;-)

Interessante, ho scritto un post su Bitcoin Italia (Gruppo su Facebook) chiedendo lumi al riguardo, e Franco (HostFat) mi ha mostrato questo topic.

Bene, dopo aver letto, mi sorgono due domande spontanee da fare:

A meno che uno faccia attività poco lecite, perché dovrei usare un sistema del genere? Cioè, come potrebbe/potremo favorire l'utilizzo di questo sistema su larga scala?

E' in arrivo anche il un ottimo client per Android Cheesy

I'm pleased to announce that the beta code of Bitseal, an Android client for Bitmessage, is now available.

      

Github:      
https://github.com/JonathanCoe/bitseal
https://github.com/JonathanCoe/bitseal-tests
https://github.com/JonathanCoe/bitseal-server

Screenshots:   
https://imgur.com/a/utC00

Working features:
   - Sending messages
   - Receiving messages
   - QR codes for addresses
   - Address Book
   - Import addresses
   - Export addresses
   - Choose which servers to use (including your own)


Roadmap for development (subject to change):
   - Update for Bitmessage Protocol Version 3
   - Lite client message retrieval using prefix filters (credit to Peter Todd for suggesting this)
   - Local encryption of the database, using SQLCipher
   - SSL for connections between clients and servers
   - POW implemented in C or C++ via the Android NDK
   - Support for broadcasts
   - Refresh the UI


Notes:

- Bitseal is not ready for widespread use yet. A full release is planned once lite client message retrieval is implemented. The app will be available on the Google Play store once this is done.

- Bitseal is free, open source software, released under the Gnu General Public License Version 3.

- Some parts of Bitseal include, are based on, or are reliant upon software written by others, including Jonathan Warren, Sebastian Schmidt, Tim Roes, Roberto Tyley, the bitcoinj developers, and the Bouncy Castle developers. This is noted in the source code where applicable.

- I have set up a few default servers which can be used for testing purposes. Anyone is free to set up and use their own. The server application is simply a slightly modified copy of PyBitmessage.

- The development of Bitseal has been a large project, taking many months of work. I'm doing it on a purely non-profit basis. Bitcoin donations are very gratefully received: 1L7amdWrPv4R4f1vLdanr2xU71TPs3wUEC

Perchè un client completo consumerebbe troppa banda e risorse per gli attuali smartphone.
Si possono usare i server forniti da loro, o metterne su uno personale, e usare solo quello.
Attualmente è sempre il client a fare la proof-of-work, ma anche questo si potrà spostare direttamente sul proprio server.


Prosegue lo sviluppo del client per Android Smiley

I'm pleased to announce that Bitseal 0.5 is available for testing! The main points of this release are:

      - Implemented local encryption of Bitseal's database, using SQLCipher. When the app is locked this protects all sensitive data, including keys and messages.

      - Finished updating the code for protocol version 3. This includes some changes that weren't available in the previous release.

      - Made numerous bug fixes and stability improvements.

As before, please note that this is Beta software, and should not be considered secure at this point. Please use it for testing purposes only! With that said, the app is currently available as follows:

1) You can download an APK file to install directly via this link:

https://drive.google.com/file/d/0BxlXwA7zWmiTSWlHemkzVUFxeTA/view?usp=sharing

2) You can join a beta testing group through Google+, which then links to the Google Play store. This will allow you to automatically receive future updates. To opt in, simply join the Bitseal beta testing Google+ 'community' using the same Google account that you use for the Play Store. Once you have joined, use the Play Store testing link listed on the community page to become a beta tester:

https://plus.google.com/communities/115838283581504499326

3) You can also compile the source code from the Github repositories:

https://github.com/JonathanCoe/bitseal
https://github.com/JonathanCoe/bitseal-tests
https://github.com/JonathanCoe/bitseal-server

If you'd like to support the continued development of Bitseal, Bitcoin donations are very gratefully received: 1ALTrxJ3Yn3Rc85Uf467u3ZcpHCzx4jDAT

Please note that I've changed the donations address to a new one, as I've been doing some re-organization of my wallets recently. All donations to the old address have been sent to the new address.

Many thanks for everyone's support so far! Your feedback is very welcome.

Ma questo progetto è ancora attivo?
Mi sembra molto interessante come cosa, anche se a quanto pare non ha avuto molto successo.
In effetti quello che mi lascia perplesso è il limite di 2 giorni oltre il quale i messaggi vengono dimenticati, anche se ciò ha il vantaggio di non dover portarsi dietro alcuna blockchain. Però boh, in effetti quello dei 2 giorni è un grosso limite.




A meno che uno faccia attività poco lecite, perché dovrei usare un sistema del genere? Cioè, come potrebbe/potremo favorire l'utilizzo di questo sistema su larga scala?
Su larga scala in effetti è un po' difficile che venga utilizzato. D'altra parte anche il bitcoin non è usato su larga scala.
Diciamo che oltre al vantaggio della crittografia (che comunque si può usare anche con le normali mail, e non è detto che la si usi per forza per fare cose "poco lecite"), la cosa che mi piace molto è il fatto di poter generare un indirizzo in 2 secondi, senza dover fare la lunga procedura di aprire un indirizzo e-mail. D'altra parte una delle cose che apprezzo molto del bitcoin stesso è proprio il fatto di poter generare in pochi secondi un indirizzo. Pensiamo invece a quante carte dobbiamo compilare e quanti dati dobbiamo fornire anche solo per fare una banale carta prepagata.


Comunque vorrei fare qualche test per vedere se questo programma funziona bene, c'è qualche volontario che ha voglia di mandarmi un messaggio a questo indirizzo? BM-2cU1nVA4rmfX1PufFTqkfL4ae7awGA8guS

Fork con diversi fix e aggiormento interfaccia Smiley

https://bitmessage.org/forum/index.php/topic,4803.0.html

https://github.com/mailchuck/PyBitmessage/releases/tag/v0.4.5

I created a new fork of PyBitmessage, and this is the first release. There were two reasons behind it.

The first one is that the user interface of PyBitmessage is bare bones and often annoying. So I integrated the changes felidosz made, and been waiting for half a year to be merged: https://github.com/Bitmessage/PyBitmessage/pull/791

Felidosz' updates were great, but not complete, there were things missing/buggy, and some annoyances were still present. So I fixed some stuff, added other stuff and improved even more.

I also tested how a normal user (my wife) is able to use the official PyBitmessage for an email gateway. She failed to even register, even though I was sitting beside her and I asked her to read the instructions on mailchuck website. She couldn't understand it. So I also spent some time on having the UI react better to an email gateway, which is the second reason for this version. Now you can register/unregister through a context menu (right clicking on an account), and the user interface adapts automatically when using the gateway, so it looks like a normal email client.

I'm still working on it, but I think it's at a stage when others can look at it and try it out. The data and config are compatible with PyBitmessage, you can switch back and forth between the two and it will continue working. There are no changes to the sqlite database, and the keys.dat config file has some new options which the regular PyBitmessage ignores. All the code is on github, I built a windows binary, and the code has been tested on linux and windows (I have no Mac).

v0.4.5.2

https://github.com/mailchuck/PyBitmessage/releases/tag/v0.4.5.2

This release, apart from minor fixes, has channels and subscriptions working in the new interface. There are still some minor bugs, and subscription folders/addresses do not show the number of new messages.
The "Messages" tab now is resizable (folder list vs the right side and message list vs the message contents.

Peter Šurda to become PyBitmessage Github collaborator with write access
https://bitmessage.org/forum/index.php/topic,4812.0.html

Chi ha sviluppato il fork precedente ora ha avuto accesso al git originale di Bitmessage.
Questo dovrebbe portare sicuramente a vivacizzare di più lo sviluppo del client Smiley

Nuova release!

https://github.com/mailchuck/PyBitmessage/releases/tag/v0.5.0

Quote
- many bugfixes and minor UI improvements. For a full list, you can look at the commit log: https://github.com/mailchuck/PyBitmessage/commits/master
- PyBitmessage will now notify you if it notices a node with a newer version. With this, you won't have to check yourself if a new version is available. Currently it will not do anything, but after 0.5.1 is released and you run 0.5.0, you will be notified if you connect to a node with 0.5.1 (or a 0.5.1 node connects to you). It only notifies once and then will keep quiet, until you restart PyBitmessage.
- PyBitmessage now again has OS X (Apple) releases. I bought an Apple just so that I can test and build for OSX. You can still run it directly by installing python yourself. My build is a done on OS X 10.11 El Capitan, let me know if it does not work on your system.

In the background, a lot of work has been done on organising the product development lifecycle. I joined the official PyBitmessage project: https://bitmessage.org/forum/index.php/topic,4812.0.html

The plan: https://bitmessage.org/forum/index.php/topic,4813.0.html is that the changes from my 0.5.x of my fork will slowly become part of the official PyBitmessage 0.6, after which there won't be separate releases anymore.
This way you won't be confused about which version to run, you will have a choice between a stable and unstable release of official PyBitmessage. I expect 0.6 to become available by the end of this year (2015).

Sta migliorando sempre di più Cheesy

Altra release.

https://github.com/mailchuck/PyBitmessage/releases

v0.5.3 (November 15th 2015):
Opportunistic TLS encryption among compatible nodes
SQLite zeroes deleted blocks
Bundled Windows / OSX executables include a working PoW library and translations
Assorted UI fixes
Blacklisting senders is easier
Network tab show sync status

v0.5.2 (November 8th 2015):
The sizes of components like account lists and addressbooks are now resizable, and PyBitmessage remembers the sizes across restarts. No more "Recieved" column stretching across half the screen! Also the saving of these attributes now works correctly on linux.
PyBitmessage now includes a library for faster PoW. You have to compile it yourself, on a Unix-like system that should be very easy. Unfortunately, I was unable find out how to include it in the binary (Windows/OSX) releases correctly yet. Precompiled Windows libraries (both 32bit and 64bit) are avalable for download for those who run PyBitmessage from python.

v0.5.1 (November 1st 2015):
There is nothing major, just plenty of small bugfixes that will make your user experience smoother.

https://github.com/mailchuck/PyBitmessage/releases/tag/v0.5.6

v0.5.6

Fixes:

portable mode on Windows now detects correctly where the binary is located. On OSX it has been improved but still not fully correct
infinite maximum acceptable difficulty was replaced with a huge but realistic setting
when running from python, button names and such are correctly localised
starting a new instance now pops up the window of the old instance (does not always work on linux though)
large messages load contents on demand as you scroll, do not freeze the interface anymore
large folders load about 6 times faster
bundled Python (for Windows/OSX executables) upgraded to 2.7.11
bundled OpenSSL (for Windows/OSX executables) upgraded to 1.0.2e. This version fixed some security bugs. I don't think that any of them affect PyBitmessage but an upgrade won't harm
and some smaller fixes
New features and enhancements

addresses and message subjects can be copied to clipboard
when replying to a channel message, you can choose to reply to channel or sender
HTML is automatically detected and such message can be switched to and from HTML mode by a single click
links in HTML can be opened, but it shows a warning (links can deanonymise you or result in you downloading malicious software)
hidden option that can prevent addresses from sending ACKs (not fully smooth yet)
users can contact support (me) directly from the interface (Help -> Contact support). It will fill out basic info about the system, like PyBitmessage version, platform, etc, so that I don't have to do guesswork.
Windows executable is packed with UPX and has smaller size
Windows executable is tested and built on Windows XP and should run on all more recent Windows versions too
OSX executable is tested and built on OSX 10.7.5 Lion, and should run on all more recent OSX versions too
More work was done on non-programming side, like creating VMs, etc.

Nuova release 0.5.7 Smiley

https://github.com/mailchuck/PyBitmessage/releases/tag/v0.5.7


Quote
This release has an overall smoother experience. Tons of bug fixes and things that have been cleaned up.

Fixes:
- Message subjects can now be copied to clipboard again and work correctly when replying to gatewayed messages
- Portable mode should now work correctly on OSX
- Windows/OSX binaries have all the system elements (like Ok buttons) correctly localised.
- external UPnP port is now remembered across restarts
- Improved unicode handling, including invalid characters
- Search text will remain after searching is finished
- Minor spelling fixes (thanks to itsexe)
- Daemon mode fix when Qt is not available. Running PyBitmessage on headless machines now works again without problems.
- Improved search method for OpenSSL libraries. For 0.5.6, some Windows users were unable to launch Bitmessage because they had an incompatible OpenSSL library somewhere on their system. This won't be a problem anymore.
- PyBitmessage shuts down correctly if you quit immediately after launching it
- Message composing will not allow rich text anymore (it just screwed up pasting, and it was ignored once you sent the message anyway)
- Sent folder shows new sent messages correctly
- Consequent spaces in message content displayed correctly
- Message quoting fixed for messages containing HTML tags
- Messages from subscriptions have the correct colour
- Addressbook editing now changes existing entries in the message list
- Labels of subscriptions and chans can now be edited also through the addressbook and update the rest of the interface automatically
- Enabling/disabling addresses updates the addressbook automatically
- Adding new entries to blacklist didn't update the list immediately
- Number of unread messages displayed more correctly
- The Windows binary now really uses OpenSSL 1.0.2e. The previous release was announced as using OpenSSL 1.0.2e but didn't, and it also sometimes included a different OpenSSL version from the system path.

New features and enhancements:
- Message contents when viewing and composing can be zoomed (Ctrl + MouseWhell, like in a browser)
- When replying, the cursor is positioned inside the message body
- Contact support form includes python and OpenSSL version
- Messages are downloaded faster from the network peers

Per chi vuole partecipare, è ora possibile fare la traduzione in italiano di Bitmessage:
https://www.transifex.com/bitmessage-project/pybitmessage/translate/#it

Uscita anche nuova versione! v0.5.8

https://github.com/mailchuck/PyBitmessage/releases/tag/v0.5.8


Quote
Since there hasn't been a new release for a while, I am making a new one. Since there isn't much work left to do before the 0.6.0 milestone, this will likely be the last 0.5.x release. If you want to make sure that 0.6 works smoothly, please try out this release and report back issues that you're having. Also, I would appreciate if people helped with the translations, I set it up on an online service Transifex so that you can do that very easily from your browser:

https://www.transifex.com/bitmessage-project/pybitmessage/

This release includes bugfixes, security improvements and some refactoring (thanks to @mirrorwish). In particular due to the security improvements I recommend that 0.4.4 users update too, as some denonymisation attacks have been addressed.

This is the list of changes:

newly arrived messages were sometimes missing or were not displayed correctly
IPv6 thread names can be correctly parsed by some logging tools
private IP range checks improved
lock file is cleaned up on exit
blacklist/whitelist labels can now be edited
don't unnecessarily send ACKs (this could have been misused for deanonymisation attacks)
don't allow getdata spamming (mitigates deanonymisation attacks)
search has been improved, now it can search without having to press return, and applies to newly selected folders and newly arrived messages
email gateway status query and settings change can be done from a menu
email gateway registration rejection messages now popup a request for changing the email address
always try all decryption keys (mitigates timing attacks)
translation system changes, fixes and updates to some translations
nodes with port 0 are rejected
HTML parser has security and rendering fixes
links for http(s) and bitcoin URIs allow an external handler in text mode also (subject to manual confirmation)
email links are handled internally (by clicking an email link, it will start composing a message to that address)
close to tray is now available
simple keybindings for quick navigation (N)ext, (P)revious, (R)eply, (C)ompose, (F)ind.
copying unicode to clipboard fixed
"Sent" folder in chans now displays both messages you sent to the channel as well as messages you sent from that channel address
multiple unicode fixes
"All identities" now has a "sent" and "trash" folder too
improvements in Tor support (reduced number of parallel connections, and PyBitmessage can now connect to hidden service nodes, but still cannot fully host a hidden service itself)
UPnP fixes
some UI refactoring (thanks @mirrorwish)
build scripts for OSX and Windows updated (I have been using them just haven't published the updates until now)

Aggiungo:
https://bitmessage.org/wiki/Main_Page

"A remote code execution vulnerability has been spotted in use against some users running PyBitmessage v0.6.2. The cause was identified and a fix has been added and released as 0.6.3.2. If you run PyBitmessage via code, we highly recommend that you upgrade to 0.6.3.2. Alternatively you may downgrade to 0.6.1 which is unaffected. We will release binary files for Windows and macOS tomorrow (2018-02-14). In the mean time, users who use binaries should downgrade to 0.6.1 using the links below.

Bitmessage developer Peter Šurda's Bitmessage addresses are to be considered compromised.

We greatly apologize for the issue and we hope to release more information as it becomes available.

(Apologies for the EN)

Code:
-        classBase = eval(data[""] + "." + data[""].title())
-    except NameError:
-        logger.error("Don't know how to handle message type: \"%s\"", data[""])
+        m = import_module("messagetypes." + data[""])
+        classBase = getattr(m, data[""].title())
+    except (NameError, ImportError):
+        logger.error("Don't know how to handle message type: \"%s\"", data[""], exc_info=True)

Yes, eval() is quite dangerous to use in almost any context other than on static, internal data. Definitely not safe to use on anything tainted by user input.

Looking at their security tagged issues, Firejail looks like a good step in the direction in general for sandboxing interactions:

Sento che Bitmessage è bello perché usa le prove di lavoro di tipo bitcoin per i messaggi, ma piuttosto ha sostituito le gerarchie di posta elettronica.
