Metamask Module

[Lalu]

Hi all, I am trying to recover a password from my old metamask wallet, I have a hash and approximate password traits but they are all 4-6 characters, if I run a hashket with these passwords and the metamask module, will the module generate passwords of 8+ characters (minimum password in metamask) if not, how can I specify what minimum password the module should generate ?

If you have a password trait with 4-6 characters, you probably refer to the ending.
In such a case it often works best to use a hybrid attack (-a7), where you have a mask in the beginning and a list of commonly used endings for you.
In case your information about the ending is less certain, you could use a hybrid attack (-a) with a word list and a mask at the ending, e.g. "?d?d?d?s", "?d?d?d?d?s etc. assuming there is a special character at the end ?d

Another way would be to use a combinator attack, in any case, I suggest you read up on cominatoror and hybrid attacks or provide more information.

For if you only care about dropping password with lower than a minimum length, you can use, the reject rule:
Reject less <N Reject plains if their length is greater than N <G *
See Rules to reject plains:

Note that when attack fast hashes, often it is not worth it to use this rule since it might slow down the attack. In your case, simply try it with a small attack to see if it will save computation time or only will slow things down.
