Hi fellow hashcats Smile

From time to time, I have the a complex hash function, like today - f(x)=SHA256(SHA256(x)) - a double SHA256 we could say, sometimes something more complicated.

My question is how do I set hashcat to help me in such case ? Can't see a dedicate mode for double SHA256.

I had the same issue once, and it doesn't seem to be supported.
One way to achieve would be to explore the code of Hashcat and apply sha256 twice.

Hardly can I believe there is no easier solution for such a common problem - hope some knows something on it Smile

You have to write a specific kernel for it
