-Name
-
-amcrypt-ossl \14 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.
