HMACCTXcopy() is not available in OpenSSL < 1.0. My optimized code won't run on OpenSSL 0.9.8. IMHO it's important to understand that some code may complete in ~100ms instead of ~30ms.

Well, I disagree about the importance of documenting a 3x difference on a select function (rather than, say, a couple orders of magnitude), but the OpenSSL version issue at least makes the situation more plausible :-)

(even though OpenSSL 1.0 is already 3.5 years old)

Antoine.
