|

|
|

|
|
*
|
|
* 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.
