Fucking Tripcode Explorer, how does it work?

How the fuck does tripcode explorer generate a random string then unix crypt it at over 1M per second?

I'm trying to do something similar but with (salted) md5 hashes, and it can only get to 18-20K per second.
I'm using a ~700ish MHz PPC processor with limited resources, by the way.

It sounds like you're doing something horribly wrong.  I can get about 1.2M MD5 hashes per second on my 2.0 GHz PPC from 2005.  Advice: Use C.  Don't call malloc.  The only functions in your loop should be initializing your guess, then md5 init/append/finish, then memcmp.
