amcrypt-ossl - crypt program for Amanda symmetric data encryption using OpenSSL
to encrypt and decrypt data. OpenSSL is
available from www.openssl.org. OpenSSL offers a wide variety of cipher
choices ( amcrypt-ossl
defaults to 256-bit AES) and can use hardware
cryptographic accelerators on several platforms.

uses the same pass phrase to encrypt and decrypt data. It is
very important to store and protect the pass phrase properly. Encrypted backup
data can only
be recovered with the correct passphrase.
OpenSSL's key derivation routines use a salt to guard against dictionary attacks
on the pass phrase; still it is important to pick a pass phrase that is hard
to guess. The Diceware method (see www.diceware.com) can be used to create
passphrases that are difficult to guess and easy to remember.
