AMCRYPT-OSSL(8) System Administration Commands AMCRYPT-OSSL(8)NAMEamcrypt-ossl - crypt program for Amanda symmetric data encryption using
DESCRIPTIONamcrypt-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
PASSPHRASE MANAGEMENTamcrypt-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
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.
File containing the pass phrase. It should not be readable by any
user other than the Amanda user.
