This page contains some simple ciphers. This was going to be extended to include some more sophisticated ciphers, but I didn’t have the time or incentive to develop this page further.

At the moment the page currently supports two simple cipher:

  • rot-13: A cipher where each character is shifted by 13 places along the alphabet
  • Holly: A cipher developed by a friend as a child. This page was made to crack that cipher for fun.
