34 calls <emphasis remap='B'>gpg</emphasis> to perform symmetric data encryption
36 &amcryptsimple; will search for the gpg program in the following directories:
37 /usr/local/bin:/usr/bin:/usr/sbin:/bin:/sbin</para>
38 <para>&amcryptsimple; uses one passphrase to encrypt the &A; data
39 and uses the same passphrase to decrypt the &A; backup data. &amcryptsimple; uses
40 AES256 as the symmetric cipher.</para>
44 <refsect1><title>How to Create Passphrase</title>
46 Store the passphrase inside the home-directory of the AMANDA-user($amanda_user) and protect it with proper permissions:
48 echo my_secret_passphrase > ~$amanda_user/.am_passphrase
49 chown $amanda_user:disk ~$amanda_user/.am_passphrase
50 chmod 700 ~$amanda_user/.am_passphrase
53 <refsect1><title>NOTES</title>
54 <para>Choose a good passphrase and protect it properly. Backup data can only be
55 restored with the passphrase. There is no backdoor.</para>
56 <para>If storing and securing passphrase in your environment presents challenges,
57 &A; provide public-key data encryption through &amgpgcrypt;. Public-key
58 encryption uses the public key to encrypt and uses the private key to decrypt.</para>
