in thread OT: Cracking hashes made easier

Depending on what the secret is used for, that might not matter. For example, if it is a password, a hashed version of my password is stored on the server. ONLY the hash is stored, not the original password. When I try to log in, whatever I type is hashed, compared with the stored hash, and if it matches I am allowed in, regardless of whether I type "ilikepie" or "iamquicheeatinghippyscum".

Yes, that's a somewhat naïve scheme, but it serves to illustrate the point.

    I don't really see what the secret could be used for other than as a salt. What did you have in mind?

      uhh, a password. You know, like in:
      login: thor password: <-- the secret goes here
        The whole point of this exercise was to say that using only the password and something that is easily derived from the user (i.e. username) can lead to attacks. So, unless I'm missing something, the password is not sufficiently secret.
