Puffer is a general purpose encryption utility for protecting your most sensitive data from unauthorized viewing. Use Puffer to securely exchange e-mail with other Puffer users, compress and encrypt your data files into zip-style PUF archives, use steganography to hide data among the pixels of image files, and distribute self-decrypting archives to non-Puffer users. Extensive wiping options are also available to permanently erase sensitive data. Puffer uses 256-bit AES encryption with 2048-bit Diffie-Hellman public keys.
