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.
