What is this?

This tool attempts to decrypt a given string using common encoding techniques by brute-forcing and sorting results based on the English language. This aims to save time for people already familiar with the various methods, however it is not recommended that beginners rely on this tool prior to learning how to identify and decode things on their own.

What can this do?

Whenever possible, the tool cycles through all possible or reasonable parameters. Each method listed provides a small variation of the cipher, which can be stacked with others (for example, a0z25 + spaceless). For descriptions on how the ciphers work, hover over their titles.
