Just to back that up:

 - OpenSSL:

	real	0m26.363s
	user	0m26.174s
	sys	0m0.188s

 - This C implementation:

	real	0m26.594s
	user	0m26.310s
	sys	0m0.256s

so I'm still slower, but now you really have to look closely to see the 
difference. In fact, you have to do multiple runs to make sure, because 
the error bars are bigger thant he difference - but openssl definitely 
edges my C code out by a small amount, and the above numbers are rairly 
normal.
