NAME

       amcrypt-ossl - crypt program for Amanda symmetric data encryption using
       OpenSSL

SYNOPSIS

       amcrypt-ossl [-d]

DESCRIPTION

       amcrypt-ossl uses 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.

       amcrypt-ossl will search for the OpenSSL program in the following
       directories:
       /bin:/usr/bin:/usr/local/bin:/usr/ssl/bin:/usr/local/ssl/bin.

PASSPHRASE MANAGEMENT

       amcrypt-ossl 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.

FILES

       /var/lib/amanda/.am_passphrase
           File containing the pass phrase. It should not be readable by any
           user other than the Amanda user.
