RDSEED wiki page and download

[Jeffrey Walton]

Hi Everyone,

We added RDSEED to the library. We reused the RDRAND gear since nearly everything was the same. That means <rdrand.h> provides both RDRAND and RDSEED.

We also reused the RDRAND wiki page. The page was modifed to discuss both RDRAND and RDSEED. You can find it at https://cryptopp.com/wiki/RDRAND . The wiki page also includes a discussion of issuing the opcodes by hand, and how to use an assembler like YASM to generate them for you.

The RDRAND/RDSEED source files are available as stand-alone download from the wiki page.

We'll have an RC6 soon since the additional functionality modified rdand.h, rdand.cpp, rdrand.asm, test.cpp and validat1.cpp.

I forgot to mention... I've got some odd configurations. I've got a MacBook that has AES-NI and CLMUL, but it lacks RDRAND. I have an Asus laptop that has RDRAND, but lacks RDSEED. So don't be surprised if you see the following (under Windows).

This isn't odd.
AES-NI and CLMUL were introduced in the late first Gen Intel Core i processors (desktop i7 and one desktop i5 didn't have it, the rest of this gen had it - at least the i5s). So chances are if you have a Sandy Bridge CPU (Intel Core i 2XXX) you have AES-NI and no RDRAND.
RDRAND was introduced with Ivy Bridge (Intel Core i 3XXX excluding 39XX series).
RDSEED was introduced with Broadwell (Intel Core i 5XXX, excluding the 59XX and 599X Haswell-Es)
The first generation with mass availability (on non-(cheap laptops)) will be Skylake (Intel Core i 6XXX) which is getting mass available right now.

So far for the little history lesson here ;)

Oh,I thought it was a bad luck on my part.

When I bought the MacBook Pro, I specially requested a model with both AES-NI and RDRAND I also loaded it up with processor cores and RAM because I wanted to use it for 5 or 6 years. I don't game or stream rich media, so I don't care about bells and whistles added to to iTunes or iMovie. The biggest pressure I put on a machine are the Virtual Machines I run.

The kip at the Apple Store told me the MacBook came with both. When I got the MacBook, I discovered it was the previous model year MBP (6 or 9 months old), and it lacked RDRAND (RDRAND started shipping one or two months earlier). I even deferred the purchase while waiting for the chips to ship. I was really pissed off about it because I spent over $3000 for it.
