This is a project I started as a freshman in college. I pick it up to play with every few years.

It's an implementation of the solitaire encryption algorithm: www.schneier.com/solitaire.html

A short breakdown of what things are:

• solpipe: Pipe text through the command line for encryption/decryption
• bench: runs through the deck for beanchmarking purposes
• hasher: mostly to keep a hash of decks for loop analysis. Don't try to use it with a large deck size
• dumper: dumps the deck through iterations
• alphabreaker: Tries to break encrypted text using iterations of decks keyed with letter strings
• numbreaker: Tries to break encrypted text using iterations of decks keyed with incremental numbered decks (not realistic)
• solitaire: ncurses frontend to encryption/decryption
