    <para>
      The <application>GPGME</application> package is a C library
      that allows cryptography support to be added to a
      program. It is designed to make access to public key crypto
      engines like <application>GnuPG</application> or GpgSM easier
      for applications. <application>GPGME</application> provides
      a high-level crypto API for encryption, decryption, signing,
      signature verification and key management.
