NAME
       amcryptsimple - reference simple	crypt program for Amanda symmetric
       data encryption

SYNOPSIS
       amcryptsimple  to be called by Amanda only

DESCRIPTION
       amcryptsimple calls gpg to perform symmetric data encryption on Amanda
       backup.	amcryptsimple will search for the gpg program in the following
       directories: /usr/local/bin:/usr/bin:/usr/sbin:/bin:/sbin

       amcryptsimple uses one passphrase to encrypt the	Amanda data and	uses
       the same	passphrase to decrypt the Amanda backup	data.  amcryptsimple
       uses AES256 as the symmetric cipher.

HOW TO CREATE PASSPHRASE
       Store the passphrase inside the home-directory of the Amanda user
       ($amanda_user) and protect it with proper permissions:

       echo my_secret_passphrase > ~$amanda_user/.am_passphrase
       chown $amanda_user:disk ~$amanda_user/.am_passphrase
       chmod 700 ~$amanda_user/.am_passphrase

NOTES
       Choose a	good passphrase	and protect it properly. Backup	data can only
       be restored with	the passphrase.	There is no backdoor.

       If storing and securing passphrase in your environment presents
       challenges, Amanda provide public-key data encryption through
       amgpgcrypt. Public-key encryption uses the public key to	encrypt	and
       uses the	private	key to decrypt.
