Hello, The attached patch adds the GOST R 34.11-94 hash algorithm. I based this code on Alexei Kravchenko's code from librhash. The original code [0] had inline assembly for x86 and x86-64 which is removed from this version.

Although this is not a modern algorithm it is being used in the russian digital signature standard (GOST R 34.11-2001).

I had issue making the test gost94-test compile. For some reason the makefile wouldn't link it against gmp (all the other tests were ok), and couldn't figure out why.

regards, Nikos
