New Pywallet 0.0.1a6

[jackjack]

Pywallet is a software I forked 2 years ago. It allowed importing addresses into wallets and dumping wallets. Since then I added functionalities like deleting keys, merging wallets and building transactions, among others.
I have planned to rebuild Pywallet from scratch for a few months now.

Some reasons made this rebuilding absolutely necessary:

• I'm far better at Python and Bitcoin
• The amount of code I added is huge and the additions lacked logic
• The code then became a mess and hard to maintain
• This prevents developpers to read/check the code efficiently
• A part of the code is from Joric and this prevents me from having a global view of the code
• The CLI and the WUI of pywallet are totally divided, so:
  
  • The features that are shared by them are written twice
  • They don't even have access to the same features
• Some dependencies are actually unnecessary
• I'd like to have a GUI

The rebuilding has now started.
Currently the plan is:

• Create unique feature declarations
• Create the CLI system and make it handle the features
• Create the GUI system and make it handle the features
• Create the WUI system and make it handle the features
• Easy update
• Windows executable (only one file)
• Make walletdump reads a passphrase
• Implement real features*
• Make a CSS for the WUI
• Use Ajax in the WUI
• Create a class instead of using global variables

The purpose of this thread is to post the progression and to read about the suggestions or comments you might have.




* Implemented features so far:

Dump your wallet
Dump your keys
Dump your transactions to a file **
Recover wallets
Import a key into your wallet
Import keys
Merge two wallets
Import a transaction into your wallet
Import a read-only address (encrypted wallets only)
Get some info about one key and sign/verify messages
Print the balance of a Bitcoin address
Delete keys from your wallet
Transaction creation

Plus those new ones:

ECDSA calculations
Dump wallets from other clients ** (Electrum, other)

** Not sure I will ever implement it

NEVER RUN A FILE I DIDN'T SIGN!
If you think one file contains a malware:

• Tell me
• Ask mods to remove the links pointing to it (see the message I signed below)
• Post a link to a virustotal.com analysis

Changelog:
0.0.1a6:
- doesn't need pywallet to run
- more info about private key
- CLI if bad --ui

Progress so far

[fpgaminer]

Very cool to Pywallet getting some much needed spring cleaning.  Besides its obvious uses, I've found it to be a useful reference for understanding how bitcoind uses BDB, quickly bringing up some ECDSA math in Python, etc.

Keep it up!

[JoeMattie]

this is fantastic.  Thank you!

[Dabs]

I'm always a fan. watch-wallet and insert-random-wallet and pretending to be Satoshi were my favorite features.

[jackjack]

Thanks for your interest guys.
Looks like importing features is rather easy so the next (last?) tricky task will be to implement the web server class I made.

It would be nice to see this on mac

It would only require python and repairing the python bsd package (broken in osx).



A few images:

Click "..."

Select wallet.dat

Click "dump"

WUI progress:


Edit:
Last version

[jackjack]

I think I finished the "frameworks" (not sure it's the correct word)

As you can see the GUI and the WUI are simple and ugly
If someone here has some graphical skills and has some ideas, please tell me what to do

Not ugly. Plain and simple. I think that is a lot better then a fancy GUI. Great project btw!

Thanks
I hope it's enough but I'm still very open to discussion if someone wants me to change that


I need some thoughts
Currently I have the old pywallet tabs (dump, import, delete, etc.) + new ones like ecdsa calculation, settings, signatures
Should I put the old ones (dump etc., which are related to wallets) in a new Wallet tab?
I supposed so

Edit:
"NPW" can be updated from CLI, GUI and WUI. The update is taken from github and is signed by a private key of mine.

[jackjack]

I still have no name for the project but an alpha version will be ready really soon. Not much features are here (see OP), it's an alpha version of the core.
Anybody interested?

Requirements:

• Python 2.7
• BSDDB (included in Python but broken on OSX)
• PyQt if you want to try the GUI

The first signing address is 1Azzay7wH1FnDE5yZMPU57y75SuT4DbGc7.
I will sign the SHA256 of the first file with this address, then once you're sure the file is ok it will check by itself when updating.

What's wrong with JackJackWallet? Even JackWallet or WalletJack sounds nice to me, and I'm not even an American, English is my 1.5st language.

I volunteer and allow you to use my name. heheh... royalty free. I just want to be famous for 15 minutes or whatever.

I have nothing against them, but it seems the latter carries a negative connotation.

(American) English is my mother tongue, and I agree that JackWallet carries a negative connotation.  I don't want someone to jack my wallet.  "WalletJack" seems less negative, but I'd still stay away from it,

And JackjackWallet is definitely too pedantic. As would be Gavin-qt or EtotheipiClient.

FWIW I like "NPW" a lot.

Not easy to pronounce

Is there a way to delete generated addresses ?

[jackjack]

Is there a way to delete generated addresses ?

Not yet but pywallet can delete addresses from wallets

[jackjack]

I'd need some Windows testers.
Normally you will be able to update later so you would only have to download it once.

[Adrian-x]

I'd love to test,
I am a noob
If I use my existing wallet.dat offline will everything work? 
If I use a copy of my wallet.dat offline is there any chance of damaging my bitcoin balances?
I'll need noob instructions to install?

[jackjack]

If I use my existing wallet.dat offline will everything work? 

Currently only wallet dump and wallet recovery work (see OP for implemented features).
It's an alpha version though so things can be buggy.

If I use a copy of my wallet.dat offline is there any chance of damaging my bitcoin balances?

No because dump and recover only read things, they don't write inside wallets.
I highly advise you to keep a backup though, we never know what can happen.

I'll need noob instructions to install?

If it works as intended, there's absolutely nothing to install: only a .exe to double-click.

Thanks for your interest. The alpha version should be ready for testers on Monday.
The "Bitcoin part" is tested and must work but I focused on the update system as I wanted early testers to be able to update without hassle.
