PROGRAMS

These programs were written for fun and education.

Lua 5.1.4 from www.lua.org was used.

nlp-cipher decodes the ciphered text by trying each rotation and scoring it based upon English letter frequencies.

nlp-shred decodes the shredded text by a greedy algorithm based upon English digraph frequencies. (It's not working 100% yet.)
