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.
