Inspiration

While working on some cryptography challenges, I realized that there are no complete tools for deciphering substitution ciphers. Most deciphering tools use basic frequency attacks and are limited to one language. Because of the lack of good deciphering tools, I decided to make my own.

What it does

Besides scanning letter frequencies, this tool has input fields for the cipher alphabet. The cipher text updates dynamically to show what the current plain text would look like using the current alphabet. Because this tool is more open ended, it allows for the deciphering of multiple languages.

What's next for Substitution Decipher Tool

Add support for non-English characters, add ability to scan digraph frequencies.
