   The Cyber Swiss Army Knife - a web app for encryption, encoding, compression and data analysis

   

   It uses a combination of magic bytes (like the `file` command), entropy analysis and character frequency detection to determine whether an output is likely to be of interest to the user.

   The file type mechanism is written here[0]. There's a list of all signatures we detect here[1].

   I also discovered Ciphey. Neat little tool indeed, but it's being deprecated. It's mentioned in this issue[1] and being replaced with Ares[2]. Neither could decipher this strange encryption[3] I used it on :(
