* SECCURE Elliptic Curve Crypto Utility for Reliable Encryption
*
* Current homepage: http://slideinc.github.com/PyECC
* Original homepage: http://point-at-infinity.org/seccure/
*
*
* seccure implements a selection of asymmetric algorithms based on
* elliptic curve cryptography (ECC). See the manpage or the project's
* homepage for further details.
*
* This code links against the GNU gcrypt library "libgcrypt" (which
* is part of the GnuPG project). Use the included Makefile to build
* the binary.
