22 amcryptsimple \- reference simple crypt program for \fIAmanda\fR symmetric data encryption
24 .HP \w'\fBamcryptsimple\fR\ 'u
25 \fBamcryptsimple\fR to be called by \fIAmanda\fR only
32 to perform symmetric data encryption on
36 will search for the gpg program in the following directories: /usr/local/bin:/usr/bin:/usr/sbin:/bin:/sbin
40 uses one passphrase to encrypt the
42 data and uses the same passphrase to decrypt the
46 uses AES256 as the symmetric cipher\&.
47 .SH "HOW TO CREATE PASSPHRASE"
50 Store the passphrase inside the home\-directory of the AMANDA\-user($amanda_user) and protect it with proper permissions:
52 echo my_secret_passphrase > ~$amanda_user/\&.am_passphrase
53 chown $amanda_user:disk ~$amanda_user/\&.am_passphrase
54 chmod 700 ~$amanda_user/\&.am_passphrase
57 Choose a good passphrase and protect it properly\&. Backup data can only be restored with the passphrase\&. There is no backdoor\&.
59 If storing and securing passphrase in your environment presents challenges,
61 provide public\-key data encryption through
62 \fBamgpgcrypt\fR\&. Public\-key encryption uses the public key to encrypt and uses the private key to decrypt\&.
