There weren't any replies to this, so maybe it's a totally dead/DOA issue, but I have seen some people talking about TRNG and PRNG recently.. so somewhat relevant.. follow-up. anyway, I ran some visual randomness tests using the MagicWand api and ripped the rngtest program out of rng-tools (Debian source), ported it to FreeBSD. So libfortuna passes the FIPS 140-2 tests (according to rngtest), and of course that's circa 2001... Anyway today I created a port and submitted it, as of r323333 (now) it's in the FreeBSD ports tree if you want to check it out. tests, images, docs, source, etc on my personal desktop machine at https://dx.burplex.com/bin/libfortuna.html despite it's age, the rngtest tool is possibly a good thing to use on miniature computing devices. or software/api expirements, if only to get warm fuzzies.(?) i do want to check out sp800-90b as the poster recommended in another thread.. looks cool. if possible build an even better testing tool. -- Waitman Gobble San Jose California USA +1.5108307875 -- Too many emails?
