Check for collision of the first few chars - HMNiLK - 05-01-2017 Hello, I just wanted to know how to crack for one possible solution of a hash following a specific pattern, for example: (SHA1) 000000XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX -> $(known salt).$(unknown integer), X's can be anything. Now I just want Hashcat, when looping through the possibilities, to check only if the first n characters of the hash are 0's, and dont check the rest. How do I archieve that? Thank you!
