  Chao cipher is nicer... Here is my implementation of chaocipher in arc lisp https://rosettacode.org/wiki/Chaocipher#Arc 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. [1] https://en.wikipedia.org/wiki/Chaocipher https://en.wikipedia.org/wiki/Chaocipher

  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. https://www.schneier.com/blog/archives/2019/10/more_cryptanaly.html https://www.schneier.com/blog/archives/2019/10/more_cryptana...
