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