Hi,
I have some about 5 million strings of the form NNNNNLYYYYMMDDXXXXX , where
N=[0..9]
L=[A..Z]
YYYY is a number between 1920 and 2000
MM is a number between 1 and 12
DD is a number between 1 and 31
XXXXX is a small set of numbers (e.g 12345, 54321, 23456, etc.)
each one has been fed to a iterative SHA256 of around 2000 rounds and I have the resulting hexdigests, so
hex = sha256(sha256(sha256(....(sha256(str)))))
I have the hashes. Is there a way to have hashcat bruteforce this? Or any way that I can use the accelerated GPU code of hashcat to implement my own brute force script?
I have tried to feed this to hashcat as:
$5$rounds=2000$$<b64 version of the hash>
, as there is no salt, but I don't really know what I'm doing here and hashcat doesn't like the hash.
Thanks in advance,
koala
