Building the CAVP Test Apparatus

2013-04-02 17:21 by Ian

The last entry gave a quick practical overview for building a FIPS capable OpenSSL. This one will explain how to compile a program against it. The particular program I will be compiling is one that I wrote to execute a set of test-vectors issued by NIST's CAVP.

Building a FIPS capable OpenSSL (Gentoo)

2013-03-08 08:24 by Ian

This is an anecdotal account of building OpenSSL with the FIPS container module on Gentoo. However, these instructions should be applicable to any other distribution with minimal translation effort. The result will be a static OpenSSL build suitable for inclusion into secure application software.
