BEDBUG

A family of FLEA-inspired CSPRNGs and Stream Ciphers, BEDBUG is a small, fast, cryptographically secure pseudo-random number generator. It exhibits uniform distribution, mixes rapidly (with worst-case avalanche better than 16-bits), has no detected bias, and comes in three variants: BEDBUG128, with an internal state array of 128+3 32-bit words; BEDBUG256, with an internal state of 256+3 words; and BEDBUG512 with a 512+3-word state. The former permit seeding with a key of up to 512 or 1024 bits, the latter with a 2048-bit key.

GA-Solve

My cypherpunk phile: A genetic algorithm method for breaking simple substitution ciphers. Probably the first used in the field for cryptology. Turbo Pascal; EXE runs on DOS. FYI: Old code, not to my standards anymore (like not seeding the RNG), but here for keepsake.
