Thanks for the reply. So I'm a bit confused as to how different crypto packages interoperate. I've been having a problem with MS CryptoAPI doing a DH key exchange with OpenSSL. There are some quirks such as byte order, and a couple other things. But for the most part, I have it working. But occasionally, I get failures which I suspect is due to the BIGNUM format of the pubkey that is exchanged. Has anybody had success getting these 2 libs working together?

Most bignum libraries use their own formats, in general they are very close (structure with words/limbs, some counters, sign variable ...). Sometimes APIs between libraries are almost the same. > How easy or difficult would it be to extract just the BIGNUM library > from OpenSSL? Are there any documents on how to do this? Very ease, but if you think about bignum library I think GMP is better than extract from OpenSSL.
