That was a cut-and-paste error on my part, not Michal's xor algorithm.

I have a library of 120 password/hash pairs and Michal's algorithm

correctly reproduced the encrypted hash for all passwords. The only

problem for me was figuring out missing elements in the "secret" array,

but as it turns out xor'ing any password/hash pair returns the key for

passwords of that length. And xor-ing the hash with the key returns the

unecrypted password. All amazingly symmetrical.
