Using OpenSSL 1.0.1l I just learned the painful way that OpenSSL_add_all_digests() is not a thread-safe function. I had been calling this in the constructor of a class providing hash functions for multiple threads. My question is, how do I know if a thread instantiating my class has called OpenSSL_add_all_digests() or not? Is there a way to query OpenSSL for the state of the table? Perhaps more importantly, is it a requirement to call this function at all? My test application seems quite happy to do SHA1 hashes without calling any of the *add_all* functions :-/ Google searches bring back about a dozen different "proper" ways of initializing, so I am asking for some expert guidance.
