LingoFish is a highly optimised OOP implementation of the Blowfish cipher, which was designed by Bruce Schneier of Counterpane Labs. It is available with full Lingo source code, free of charge.

After encrypting data with LingoFish, you may find you are unable to do anything with it, because FileIO corrupts the data and you cannot send it with postNetText either. You need base-64 encoding.
I have now added my PHP implementation for download. Just extract onto a webserver with PHP installed to access the instructions and utilities. This will allow you to communicate with between Lingo and PHP if you do not have mcrypt installed.
