  Comments from Solitaire's author, Bruce Schneier:

  > I don't talk about it much, mostly because I made a dumb mistake that resulted in the algorithm not being reversible. Still, for the short message lengths you're likely to use a manual cipher for, it's still secure and will likely remain secure.

  Chao cipher is nicer...

  Here is my implementation of chaocipher in arc lisp https://rosettacode.org/wiki/Chaocipher#Arc

    Chaocipher is thoroughly broken (see the citations on Wikipedia[1]) so it's not really comparable to Schneier's algorithms.
