Bitcoin wallet. Dat Purse 2010. Forgot the password from memory I remember it was bitcoin core. How do I decrypt a password are there any people who do it? Leave your contacts and feedback

You can always install btcrecover and attempt to find the password yourself. It's a free open source project. It all depends on how accurate you are with your information, and how much you know of the password.

If you believe there's only a typo or you are missing a few characters then it should be somewhat solvable using different techniques on btcrecover. If you don't know the password and have no idea what it could be then it's going to be close to impossible if the password isn't weak.

You can test directly against the wallet.dat file that you have, or if anyone else helps you then you can extract the mkey and give them that to avoid them having access to your wallet if they guess the password.

It's just that the purse is seven years old and I've forgotten everything, so I'm looking for a professional who can help.

I suggest start by loading Core, letting it download and running it. Play with it a bit every day or two for a month or two. You might wake up one morning and remember your password.

Has anyone ever tried a hypnotist?

Well, it you used a weak password then it may be possible to brute force it. But, if you haven't then you've likely lost access. You should put yourself in the situation when you first made the wallet to see if this reminds you of anything.

You could contact a few people who can attempt to crack it for you, and provide them with other passwords which you have used in the past to identify the patterns you use and go from there.

if there's a way to decrypt your password then using a password is useless in the first place
the only way I know is brute force method with massive computational power
and as mentioned before, there are few services that can help you with that

or try his suggestion...  ;D

That's not bad, and you can get your coins back someday... for sure

My 2 cents here is to "MAKE A COPY OF THE WALLET.DAT BEFORE YOU DO ANYTHING",

good luck, you millionaire  8)

Don't you have any clue about the possible passwords?

If not, then I'm afraid your chances are very low because none of the wallet recovery services are doing brute forcing without any password clues.
It's their policy to prevent them from working on stolen wallets.

You can use btcrecover yourself but it will take ages to brute force the wallet if you don't have any clue about the passwords.

IF you do have clues of possible passwords you used in the past and/or there's a pattern in how you usually create passwords, there's a very big chance you'll be able to recover it with btcrecover.

In the later case, let me know if you need help with this.

As previously mentioned, btcrecover would be the way to go.
But you have to remember at least something from your password.

I want to add something very important which hasn't been mentioned in this thread yet:
Do NOT give your wallet file or any other sensitive information to random people posting here / PMing you.

For example, this one is spamming his 'recovery service' in every thread regarding lost passwords, even if those threads are 2 years old:

A newbie, who 'offers to help' with retreiving passwords is not trustworthy at all:

Those are 2 examples of untrustworthy 'offers'.
90%+ of PM's you will receive from people 'ready to help you are scam. Don't fall for them.

Agree with the response provided here.
Users here can provide feedback as to how to use BTCRecover if you need help with the steps - but never send your wallet to anyone.
Technically he could try to use BTCRecover with no knowledge of his previous password but this is usually futile due to how many passwords exist.

Do you remember if you created the password or if it was generated? If it's the former, think about various things going on in your life at that moment. Scroll through your inbox for that period, look at your bank statements, look at your iPhone photo gallery. Jog your memory about who you were at that point in your life and what you were going through. Write down all of that in a simple list. PM me for more details.

You could try pywallet as well. I know of several people who were able to recover their passwords in this way.

Also, whoever suggested a hypnotist, that might not be a bad idea. Given that you're offering 10 BTC, it must be a pretty large balance. A hypnotist wouldn't even cost you a tenth of that, and the various recovery tools will only cost you time and effort.

Also, just to reiterate, 99% of those offering to 'help' by wanting access to your wallet.dat file are going to steal your shit if you give it to them. And you really have no idea who won't. Be really damn careful. And if you are successful in recovering it, IMMEDIATELY move it. Just in case.

What? No.
A password would be completely senseless if you could just right click and "look at the details" to retrieve it.
The password is not stored anywhere on your PC.

The private keys are encrypted with a (fully random) master key which is encrypted with AES-256-CBC with a key derived from the passphrase using SHA-512
and a dynamic number of rounds (depending on speed of the computer which does the initial encryption).

You can try using Hashcat with JTR if you have a fast machine to do the calculations.
This is what the wallet recovery services actually do. Extract the hashed password and try to bruteforce it.
Make a list of the passwords you used from back then if you have any - try very old forum passwords, make a list with different capital and lower case letters, numbers you usually use. Never give your wallet file and password list to anyone you do not trust. Good luck!

This post seems pretty fishy to me... Stay safe and dont give information to people just like this one !
