I don't understand the technical side of recovery at all, but I read that in some cases such passwords can be recovered using brute force or dictionary attacks (tools like btcrecover, hashcat, etc.), especially if one can recall at least the approximate structure of the password.
I hope that this isn't the same case as your previous thread.
Anyways, that dictionary attack only works on weak passwords generated from common words, slang, phrases.
If the service/you run it with a good word list and there's no result, the only option that you have is to remember a large portion of your password.
You may proceed if you're certain that some of your partial passwords would work with alterations (
typo and additional characters).
Now to actually get help from the community without needing to share the wallet file,
Research on how to extract the so-called "
hash" from your wallet file so that anyone who's willing to bruteforce it can give it a try without sacrificing your wallet's security.
To understand how it works, in simple words: that hash contains the encrypted master key that's when decrypted, used to encrypt/decrypt your wallet's private keys.
Since it's just the encrypted master key (
plus other necessary data for its decryption), it's useless to those who've successfully decrypted it, they still need the encrypted private keys from your wallet file that you shouldn't share.
Here's a tutorial on how to extract it using old (
gurnec) BTCRecover's extract script:
github.com/gurnec/btcrecover/blob/master/docs/Extract_Scripts.mdThere are a few ways to do that using other tools, that's just one example.
