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.
