I wrote this as a simple front-end to the crypt_blowfish class of the PEAR project. Blowfish encryption uses a given pass-phrase to encrypt a message. The output looks like garbage text to anyone who doesn't know the pass-phrase. I have further wrapped the output of the blowfish in a base64 encode, so that it can be nicely transmitted via e-mails and IMs without nasty characters getting in the way. Feel free to use this to send messages that need to remain private.
