Hi all,
Im quite new to using Hashcat.
My first database I happen to have Im testing against to which I also have the source to how it was hashed is proving more difficult that I thought.
It has been hashed twice as follows. (there is no salt)
$Hash1 = SHA1([password-to-hash);
$Hash2 = SHA1($Hash1);
Now $Hash2 contains something like "FF 12 FE ........" in Hex etc.
Now Hashcat can have a go at this now with the right parameters even though its doubled. (I believe).
The problem I have is that the Hex output of the double hash has been converted to a base 10 Decimal number and that is what is now the hash.
i.e. "FF12FE...." will become: "25518254...." which without some sort of delimiter I cannot convert back to Hex again. (without coding something)
Is there a way to deal with this within Hashcat or do I need to go off and create my own rainbow tables maybe.
