  33 <para>&amcryptsimple;
  34 calls <emphasis remap='B'>gpg</emphasis> to perform symmetric data encryption
  35 on &A; backup.
  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>

  45
  46 Store  the  passphrase  inside the home-directory of the AMANDA-user($amanda_user) and protect it with proper permissions:
  47
  48    echo my_secret_passphrase > ~$amanda_user/.am_passphrase
  49    chown $amanda_user:disk ~$amanda_user/.am_passphrase
  50    chmod 700 ~$amanda_user/.am_passphrase
  51 </refsect1>
  52
  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>
