+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.
