The top plate in the radio box holds the bulk of the custom circuitry for the car computer. Mounted to it, we have the public address (PA) amplifier, the DC/DC for the amplifier, my hand-built filter and audio-level shifter, the main CPU board, the audio board, and a handful of regulators and MOSFETs.

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.
