is there a way to recompile hashcat with this constant 256 replaced by 1024?
it is ok if it is slower.
or is 256 a real gpu hardware limitation?
would hashcat work with:
md5(known_fixedpart_len300 + pwd_len_max_256)
the fixed part of length 300 is always the same, and the generated passwords are of length less than 256.
at the end it is always md5(more than 256 char), i dont know if the fixed part changes something.
