Passphrase recovery

[houseo]

I sent my information to a recommended bip38 passphrase recovery specialist.

I had a good idea of what the phrase was. At first he was quite responsive, but of late I have not heard anything back. The coins are still in the wallet but I'd like to recover them, or at least know of how the attempts are coming along, but the communication lately has disappeared. I guess there's not much I can do, just feel like venting.

no, not at that point. i still have faith. i mean it may be the coins are not recoverable, which is unfortunate, but I'd at least like an update on how the passphrase cracking attempt is progressing. it's been about a month.

A month such a short time make take months or years to recover. How long was your passphrase anyway?

Agree, the wallet would need to be "brute forced" cracked which is currently not an option for bitcoin wallets, especially if it was more than a handful of characters long. The bitcoin wallet encryption is strong by design. To brute force, we need to be able to do millions of attempts per second. This is currently impossible for the bitcoin wallet. A general quad core i7 computer can only makes 10-13 attempts per second.

However, if we have a good idea of the password (and also the length of the password), then it won't take months or even weeks to break it. Hopefully, he knows what the password should have been but maybe he is one character off or the capitalization is off. These common mistakes are the most likely reason that he is locked out of his wallet. Dont be worried, I can offer you some helps.

To brute force the entire 8 digit winrar password with 96 charset (mixed upper and lower case alphabet plus numbers and common symbols) will take about 229 years (7.2 quadrillion password combinations)
