      To use this program for its intended purpose (see <xref

766
      have to be given out to be stored in a server computer, after

      having been encrypted using an OpenPGP key.  This encrypted data
768
      which will be stored in a server can only be decrypted by the

      however, is stored unencrypted on the client side in its initial
