Program Description: CRYPTANALYSIS HELPER aids in decoding simple substitution aristocrat ciphers, i.e. each letter in the original message is replaced throughout by a unique cipher letter code. It suggests translations based on a comparison of standard letter frequencies with the frequency counts of the first letters of words, last letters of words, all letters, and one letter words in your secret message. It matches words with some letters decoded with its dictionaries of words. Each dictionary lists words of a specific length. Written in C for MS-DOS, the documentation does not list system requirements or limitations.
