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.
