Subject: Tripcodes, take 2


So, as a favor to a friend, I'm committing myself to getting tripcodes
into JtR. I was stymied last time by a confusing facet of the format
system: There's no way to specify that a hash might have multiple
possible salts. Tripcodes always have 3969 possible salts for any
given ciphertext, corresponding to a mapping of the second and third
characters of the plaintext. (Specifically, they are mapped down to 63
possibilities per character, and 63**2 is 3969.)

However, I noticed that, for DES, there is a "many salts" message
during benchmarking. I can't help but be curious: Is there a way to
tell the DES cruncher to try a variety of salts for a given

Obviously, I could rig up a shell script that simply spins JtR several
thousand times for a given tripcode, but that seems kinda silly. :3

Thanks in advance,
~ C.

When the facts change, I change my mind. What do you do, sir? ~ Keynes
