decipher-mode is an interactive autoloaded compiled Lisp function in `decipher.el'.


Major mode for decrypting monoalphabetic substitution ciphers.
Lower-case letters enter plaintext.
Upper-case letters are commands.

The buffer is made read-only so that normal Emacs commands cannot
modify it.

The most useful commands are:

D Display a list of all digrams & their frequency
F Display the frequency of each ciphertext letter
N Show adjacency list for current letter (lists letters appearing next to it)
M Save the current cipher alphabet (checkpoint)
R Restore a saved cipher alphabet (checkpoint)
