cypherpunks/cryptanalysis/README This directory is for cryptanalysis tools for both ciphers and implementations. There are plenty of bad ciphers around, and even a good cipher can be badly implemented. Tools of all kinds are solicited. There are two cracking programs available for Word Perfect (bad cipher). There is a file on cracking licensing schemes (bad implementation). There is a cracking program for encrypted pkzip archives; here we have a brute force attack available. Eric
