Having said that, if you feel strongly about this, I will change zchunk so openssl is an optional dependency, that, if available, will provide the hashing functions rather than the built-in hashing functions.
Do you feel that that would be worth the effort?
Having looked at OpenSSL's API, this should be a very easy adaptation, so I think I'll go ahead and do it. It's reaching the end of the day here, though, so it probably won't be ready until tomorrow.
