Subject: How to increase Max Length? / Very long passwords
Hi, so I’m aware that what I’m trying to do might actually be impossible but I still want to try and find a way because it’s just for fun so why not.
I hope I can explain this all well.
I’m trying to crack an sha256 hash, but the password itself is an sha256 hash.
For example:
If the hash is e0bc614e4fd035a488619799853b075143deea596c477b8dc077e309c0fe42e9
then the actually password would be 6b86b273ff34fce19d6b804eff5a3f5747ada4eaa22f1d49c01e52ddb7875b4b.
The main problem I’ve come across is just the length of it. Prince mode won’t try to crack anything with a Max Length of 32 and Markov won’t try anything over 30.
Is there a way to change the Max Length to more?
The reason I tried to use prince was I made a wordlist that broke up the permutations into groups of 8. Eg: aab3d7ef. If I could get it to try every combination of 8 of these (8x8=64) randomly then maybe it would just stumble on the password.
Ideally I think if there was a way to just keep hashing the last attempt over and over it might stumbled on the password too. Eg: if it tried
e0bc614e4fd035a488619799853b075143deea596c477b8dc077e309c0fe42e9
then
d6a804981ea7ce374acc21c9a8bf82f50b684b0ea4bdf8b26a7a775291aaf7a6
then
ad376767fc04814220cc25c79b2777cd14704f23f1830318b5bd9eb97e4fedf6
perhaps that would be quicker?
If anyone has any other ideas that would be great!
I’m just doing this as a hobby after finding some interesting articles on hashes and cracking etc… so my knowledge isn’t heaps.
Cheers
