Precomputation

[anyconnect]

Hello,

I want to precompute a hash that is fairly slow and is not salted. How can you precompute the values of the hash and still have the cleartext value of the password? That way you can feed hashcat just the hashed value and won't take nearly as long.
How would you do that?

Not supported. The technique you're looking for is called rainbow table.
