It might be interesting to compare the speed of this library with the speed of the multiprecision code in RSAREF and in PGP. May the fastest library win!

Version 1.3 of the GNU Multiple Precision Arithmetic Library is now available for anonymous ftp from prep.ai.mit.edu as /pub/gnu/gmp-1.3.tar.z.

Well, I've done some comparison between gmp 1.3 and RSAREF (as distributed with RIPEM 1.07) on a RS6000/320 The key generation speeds turned out to be almost exactly the same using the "aixgcc/xlc mixed" version of RSAREF/RIPEM and gmp compiled entirely with IBM's xlc compiler. (for those who haven't poked around in RIPEM, I'll say that this RS6000 version of RIPEM uses the "long long" data type to get 32 bit by 32 bit multiplications with 64 bit results quickly). So, it wouldn't surprise me if some clever person could optimize gmp for the RS6000 and end up with something faster than what's provided in RIPEM 1.07.
