Blowfish is an encryption method that uses a simple pass-phrase to encrypt and decrypt the message. The output from Blowfish contains characters that are not web-safe, so it is necessary to further encode it as Base64 (or something similar) if the encrypted message is meant to be shared via e-mail / IM / etc. This tool allows you to encrypt and decrypt messages with Blowfish, the encrypted output will be provided as Base64 encoded text. While this may be used to send secure messages, please be aware that this site is not encrypted (no SSL), so communications between your browser and this server are in plain-text. This tool was written in August, 2006.
