RainFish is an easy-to-use high security text encryptor and password manager. Its primary function is to encrypt email text for in-line transmission, while emulating the functionality of public-key encryption systems. RainFish uses the algorithms Rijndael (the new Advanced Encryption Standard), Blowfish, and PC1 to encrypt and optionally sign messages with a digital signature. Includes anti-tamper and antistealth features, and a built-in password manager. May be run entirely from the tray.
