/* 
 *   SECCURE Elliptic Curve Crypto Utility for Reliable Encryption
 *
 *              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). The code compiles successfully with 
 * libgcrypt 1.2.2. Use the included Makefile to build the binary.
 * 
 * Compile with -D NOMEMLOCK if your machine doesn't support memory 
 * locking.
 *
 * Report bugs to: seccure AT point-at-infinity.org
