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