What do you mean by "use multiple cores"?  I would assume all of them do by
default, in that they can be scheduled across any number of cores.  If you
mean "does the SHA-1 implementation of library X use all cores" then the
answer is that none of them do, because SHA-1, and indeed most crypto, isn't
parallelisable outside of some special-case modes like CTR/GCM.

Even then, what problem are you trying to solve that requires more than, say,
50Gbps throughput (Intel's figures for AES on a 16-core system)?
