Substitution Ciphers

To begin, please enter the ciphertext or plaintext you would like to work with:

Please note that this is not as advanced or user-friendly as the locally-running substitution cipher program Cryptoslam, which is available as a Java applet that runs in your browser or a downloadable version to run locally. On the other hand, this version runs with zero effort in any web browser, with or without Java, and does not require downloading, compiling, installing, or mucking around in a command-line terminal window.
