Since you said you enter it everyday for 1.5 years, i feel it's far more likely the header got corrupted.
I also suspected this is the case, but I have no idea how it must happen by accident. Header corrupion usually happens when improperly configured Windows tries to initialize encrypted drive and overwrites header. How it can happen on laptop going to hibernation I do not know. Cosmic rays hit my RAM chip maybe? Also, the computer have 2 hard drives encrypted with same password. Both drives do not accept password, I deduct that it is wrong password, not corrupted volume header at play.

I recall hibernation dump RAM content to the disk and load the dump to RAM once hibernation ends, so i doubt it's cosmic rays hit your RAM. And since you mention 2 drive, header corruption become unlikely. But just in case, have you checked S.M.A.R.T. status of both drives?
Have not checked after the incident, but I checked them at least one a month and they both were in great shape and also worked flawlessly. So the problem is not some sort of hardware failure.

Have you tried using win pe to get the bitcoin file?

I know a lot about computers, forensics, data rescue, repairs, troubleshooting, administration. If WinPE would get to my wallet file, I would use it.

You wrote that you relied on muscle memory, but it was damaged after injury?  Perhaps hypnosis will help you?
An experienced hypnotist can mentally transport you back in time and “give you a verbal command” to enter the correct password.  Your muscle memory may be blocked, but it is not gone, so it is possible that you will be able to decrypt your computer.  And then the hypnotist will bring you out of the altered state and you will change the password to a new one (which you will write down in a paper notebook). 
Yes I relied on muscle memory. No, I sligtly bruised my leg, not arm or head. I was only stressed, studying before exam, and very mild infection of common cold. It appears it is enough to lose the muscle memory. Also I live in a place where there is no hypnotists or similar charlatans available. I am also very resistant to suggestion and hypnosis, discovered that after friends invited me to religious sect where the priestess attempted to scare me, hypnotize and other tricks just to later privately admit that I am crazy or psychopath and completely immune to contact. It will not help. Also, the password was lost in February 2016 so pretty much time have been passed since then.

In general, it seems that crypto enthusiasts very often lose access to their Bitcoin wallets precisely because of their paranoia, due to overly complex passwords that they forget.
Because the story you told is not the only such case.
There are lot of stories when people forget the encryption password or damage the key material and lose their files. But they are just files. There are also even more stories where people make some dumb opsec mistakes and FBI rummage trough their filesystems and smear them with shit in court. And they lose the files as in first example plus their freedom in addition. And then there are few examples where people encrypt their devices properly AND refuse to give password and eventually they go free. The fact that You or I have paranoia does not mean glowies are not after us.

This is the sort of thing that I'd store in a password manage though. Just saying.
I use KeePass on my computer for all sorts of passwords, but obviously preboot authentification password should be stored somewhere else. I could try to find old keepass database file on my old backups in hope that it contains the password in question but I first need to get the drives recognized and unlocked. They are failing or failed, IBM Deskstars GXP120
OP

Here is an example to bruteforce your password with hashcat or Johntheripper:

1. Lets say the password is "Bitcoinlover184%"

The only part of the password you remember and are sure about is that it contained "bitcoinlover" and maybe you remember the lenght or approx lenght.


You could either use the mask attack like this ?a?a?a?a?a?a?a?a?a?a?a?a?a?a?a?a

This would find your password but you would need an Extreme amount of GPU power.

Rather, like i would do is implement a couple of statistically proven password rules and it would be this:


Dictonary + bruteforce attack

1. put bitcoinlover in wordlist

use masks on the password. For example:

?H?itcoinlover?d?d?d?a

This mask would crack the password very fast but is not realistic as we dont know all the Details of the password. This is just meant to show you how easy it can be to crack passwords.


Thank You, as I read Jack the Rapper documentation it might help. First I envisioned the JTR running under BAT file control, but now I also discovered software that takes wordlists directly and works with TrueCrypt and DiscCryptor under Windows. Now only the question is a good wordlist that contains my password from the password I remember and have written down.

You all are making things unnecessary complex! Just copy wallet.dat to Bitcoin data directory and run Bitcoin Core. Old wallet formats work with latest Bitcoin Core versions. Forget about pywallet it is for recovery of damaged or lost wallets and keys!

Your post is very hard to read: you didn't mine Bitcoins, then you did, then you're copy/paste something completely irrelevant about Electrum. I'd say try again, make it clear what you're asking.
I think it is output from AI chatbot that have been trained on posts of some random guy from India. Or he is completely clueless and stumbled upon computer with old Electrum client...
5  Bitcoin / Bitcoin Technical Support / Re: time to re-sync a full node after power-outage on: May 18, 2024, 12:39:53 PM
Hello,

for the case there should be a power outage, will the entire blockchain be downloaded again or only the changes (since the outage)?


Thank you!

Most commonly a power outage results in irreversible corruption of data bases relevant to blockchain copy on you disk thus IBD will be inevitable fact of life if you don't have the backup.

I have backup 2TB SSD disk (which I  synch on regular monthly base)  for such cases. Thus should the outrage happens I will copy the content of this  disk to SSD which is attached  to my bitcoin node.


I think UPS or replacement battery is cheaper than 2TB SSD and also a better solution. Losing power can lead to data loss and silent corruption all over system, not only Bitcoin.

Did you enter your password from memory every day for 1.5 years, that is, 547 times, and then forgot it?  Here we can say unequivocally - you REMEMBER your password.
I probably did not enter it every day, but sometimes it went without entering the password for week, sometimes I entered the password multiple times per day when installing and rebooting. I am pretty confident it was at least 350 times over course of the usage of that computer. That unhappy day I hibernated the computer at morning, went to study, returned home, powered the computer but it refused my password I entered multiple times. That was stressful time in my life - study and exams, relationship issues, and that day I slipped on icy road and slightly hurt my leg (not head!). I entered the password mostly from muscle memory, because it was 28 or more random characters, upper and lower case, numbers and special symbols. As it turns out the brain is unreliable storage medium.

The incident happened 8 years ago. I left the computer as-is and counted the data as unrecoverable. Because I made it to be immune against seizing and decryption attempts by KGB, FBI, CIA and NSA. But now I want to restore the computer as it was because it is in very good physical condition and very great example of that era ( HP Pavilion dv8000) and I have the the disk images to play with and spare hardware to run brute force on.

Of course I have created disk images and working on them.

A tool that creates wordlist from mangling given passphrase also would be workable. In fact it could be much better since it will be simpler for me to implement in bat file.

I have this DiskCryptor 0.9.x encrypted computer that I only partially remember password. I used this password for every day for like 1,5 years and one not so good evening I came back home, entered the password and it was not accepted. Tried various combinations, maybe I missed some letter or wrong case. Nothing. I am pretty sure that the encryption is not malfunctioning or somehow gotten corrupted. It is the password that got some bit flip in my brain. It got not only several bitcoins stored on that computer, but my digital life for almost decade that is locked away - pictures, music, game saves, everything.

I have the password written down after the incident as I remember it. Obviously, it is not the exact correct password. I think that John The Ripper is best software that can do various permutations on a text string given, then feed the output into command line of diskcryptor and depending of diskcryptor returned status repeat with new password or print out correct password. All could be controlled with BAT file.

I need some ideas and general discussion. Maybe someone have better software that can manipulate a password. I have no backups, the setup was super paranoid and secure.

Although i also wonder whether Bitcoin Core actually support Windows 7 or 8.
Running Bitcoin Core 27.0 64-bit on Windows 7 SP1 64-bit right now without issuses. I confirm it works.
Quote
I'm curious, which feature you're talking about?
New transport protocol, new wallet formats and options. These are the very basic of Bitcoin that should not be touched without great necessity and majority consensus. Imagine I go to prison for 10 years. Or join army. Or enter coma after colliding with train. When I get back to my computer I should be able to turn on my computer and sync the Bitcoin client right away. Bitcoin now have become a value storage medium in addition to tool for transactions.

Would not C++20 requirement cause C++ runtime files being required on Windows and in turn not working on Windows7 or 8?

Also it appears that Bitcoin have catched mild form of featuritis causing bloat without reason.

Learn how to use computers, guys! You cannot become infected without pilot error from your part! Or You must run misconfigured AND vulnerable system for it to happen without user interaction.

Telling I got infected despite running Defender is like saying I got raped despite having condoms in my pocket. First, to get raped it is Your fault to get drunk and then pass out near active gay pride. Second, to get Your computer infected it requires equally stupid action from Your input.

Do NOT run any executable on Your computer without verifying it is 1. Legit software, 2. the file checksum or cryptographic signatures is correct.
Do NOT give remote access to computer. Do not use proprietary remote desktop solutions, ever!

Generally it is safe to open links in scam e-mails with fully updated and securely configured system. Just to see them for amusement.
Also it is safe to run malware and unknown software inside isolated virtual machines. Just be aware that software can act differently under virtual environment versus real computer.

The lack of grasp on how things work in this discussion is evident. The hardware security devices will not protect your bitcoins if You run stuff downloaded from internet and have no clue what it does. Fool and his money will inevitably be separated sooner than later. I suggest one of two actions:
1. Hang around internet forums and learn how computers and hacking works in reality
or
2. Since You will lose your money anyway, why not make some benefit out of this fact and send the bitcoins to address in my signature rather than lose them at inappropriate moments to some subhuman scammer.

I suggest that starting from April 1st Bitcoin itself should be banned in this forum. Because of money laundering, terrorism, child porn, anti-Big Brother etc. usual bullshit.

What a sellout and pussy is the current owner of this forum. Show me a law that explicitly says that writing a URL is crime. Show me a law that states that talking about crypto mixers is a crime. Probably there are such laws in some totalitarian states. Then just move the forum to somewhere where it is allowed to discuss these things. Not discussing good and bad mixers will only benefit scammers to advertise their scam service trough facebook/instagram/google ads and delay bad reviews to build up. People will use mixers anyway.

Best thing to do is just forget about coins. No life or limb is lost. This also happened to me. I forgot encryption password for hard drive of computer. And I miss the pictures and saved games more than the bitcoins stored there. Just we must take lessons how other people failed and not repeat them.

Also I feel good that the destiny got Luke for hacking CoiledCoin. It is hard to feel sympathy for a guy who looks like crossover of Amish husband and feces-smearing Johnny Knoxville. And Luke over years have acted as one, from genuine service to humanity as a free software developer to destroying altcoins and smearing blockchain content. Luke is like my cousin. My cousin is brilliant scientist and computer hacker, but complete imbecile in human relationships and behavior.

22.1 and 23.1 are bug fix releases for the previous major versions of 22.0 and 23.0. They contain bug and security fixes that were backported on top of older versions. The purpose of such releases is to allow people to still safely use older versions. Users may still wish to do so because they may still be auditing newer versions, or newer versions contain features that they are not yet comfortable with, or maybe something was deprecated and removed that they are still relying on. In these releases, very little has changed except for some bug fixes that were deemed to be important.
It was never done such for Bitcoin. So the there is real base for concerns some users about full RBF feature that developers decided to basically continue to work on older releases?

Quote
Minor releases has nothing to do with "soy milk drinking wannabe programmers cannot get even the version numbers straight". It is, in fact, a standard procedure that we do, and is a common practice in the software development industry.
Standard practice was to release 2.0 version after 1.x is abandoned and in Visual C++ 6.0 New Project menu is selected. I remember Bitcoin always had 0.xx.x versioning schema until someone dropped zero from front and we arrived from pre-1.0 versions to version 22 overnight. If this is not Firefox then what? Also some Intel fanboys decided to rename Bitcoin to Bitcoin Core. And do not tell that Bitcoin and Bitcoin are two different things. The reference implementation of Bitcoin De Facto are Bitcoin. Just like when we are talking about DC++ there is no need to separate DC++ protocol from DC++ client, even if the protocol is compatible with other clients like RevConnect or StrongDC++.

Quote
Just as an example, the Linux kernel is currently 6.1.2. But there are still releases for 5.x and 4.x kernel versions because they support older major versions. They make bug fix backports to the older versions so that users who wish to still use those older versions are not left out to dry if there are important bugs that are found.
If I want to run 2.4 or 2.6 Linux kernel versions, I take out old Slackware or Mandrake CD-ROMs and run them. Also Linux stayed on 2.4 and 2.6 kernel versions for long time. I do not remember 2.8 versions, but probably because I mostly work with embedded systems now. Even Linux kernel development now is infested with soy drinking transvestites messing up version numbers.

So where we are now? What is the bestest Bitcoin version?

For example, using USB storage to transfer unsigned and signed transaction could  be exploited by specifically designed malware.

Everything looks more than sloppy for a Bitcoin Developer. Surreal. Hot wallet is possible, but a dev's cold wallet... hmm...

While Peter Todd has confirmed the story, also on Twitter, I find it incredible and I still tend to think that's higher chance both Twitter accounts (Luke-Jr and Peter Todd) are compromised than all this story (including Luke calling on Twitter for FBI, come on...). Even more, no sign of this story on his Mastodon/BitcoinHackers account.


Do not attack me for this, however for the skeptical me, another argument mentioned in Luke's thread that made sense was it was done to make everything appear like a hack so Luke can use it to write off taxes. Before you shake your heads on me, I am only saying it makes sense, I am not accusing him. I know Luke is a religious and a God fearing person who will never do something shameful only to avoid paying taxes. If this was Justin Sun it would be different hehehehe.
God ordered to hide his taxes from heathen government. Also God commanded him to hack CoiledCoin as well as smear blockchain with religious ramblings.

Being religious does not make person or his action good. Crusaders are perfect example from history.

It's definitely a sign that none of the cryptos at just a singular place is safe, no matter if it is in your ledger or on your pc or anything else. Singular place is always terrible.

Many people claim that "not your keys not your coins" because of exchange hackings, but at the same time if you end up putting it on binance, do you really think that binance will be hacked so big that they will fail to pay the customers? They have so much money that you could empty all of their hot wallets today, and their cold wallets would still cover everyone's funds. That is why I highly believe that they are going to be the best case if you want to safely secure your coins.
You could just send your coins to me for safekeeping. I also will not bend to LEA if ordered to freeze your coins. Single place is OK as long as it is only Your control and nobody else.

Am I only one who find this amusing? Remember, Luke Dash-Junior is the fukker responsible for 51% attack against CoiledCoin by abusing mining pool power controlled by him.

Also, still nobody managed to hack me and steam my coins. And I am confident that nobody will be able. I am better in computer security than Luke.
