Puffer is a general purpose encryption utility that is used to protect your most sensitive data from unauthorized viewing. You can use Puffer to securely exchange email 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.
