How to install nistp224

Like any other piece of software (and information generally), nistp224 comes with NO WARRANTY.

System requirements

nistp224 works only under UNIX (Linux, FreeBSD, Solaris, etc.). However, the nistp224 library could easily be ported to other systems.

On x86 processors (386, 486, Pentium, Athlon, etc.), nistp224 works only under gcc. However, the asm output could easily be used with other compilers.

The x86 development tools in OpenBSD have inadequate support for -malign-double. nistp224 will work under OpenBSD, but it will be unnecessarily slow. You can fix this problem by installing GNU as and GNU ld.

Installation

Create a /package directory:

     mkdir -p /package
     chmod 1755 /package
     cd /package

Download nistp224-0.75.tar.gz into /package. Unpack the nistp224 package:

     gunzip nistp224-0.75.tar
     tar -xpf nistp224-0.75.tar
     rm nistp224-0.75.tar
     cd math/nistp224-0.75

Compile and set up the nistp224 library and the nistp224 program:

     package/install

The compilation process includes some regression tests; it will stop if the tests fail.
