  29  *   SECCURE Elliptic Curve Crypto Utility for Reliable Encryption
  30  *
  31  *              http://point-at-infinity.org/seccure/
  32  *
  33  *
  34  * seccure implements a selection of asymmetric algorithms based on
  35  * elliptic curve cryptography (ECC). See the manpage or the project's
  36  * homepage for further details.
  37  *
  38  * This code links against the GNU gcrypt library "libgcrypt" (which
  39  * is part of the GnuPG project). Use the included Makefile to build
  40  * the binary.
  41  *
  42  * Report bugs to: seccure AT point-at-infinity.org
