Looks like you've been busy! I was going to ask why these updates aren't being pushed an OpenSSL repo shared with Squeak, since things should not be much different at this low level, but actually it was hard to determine which was the original repo. I see... http://www.squeaksource.com/SqueakSSL.html seems to have not beenupdated since 2012. cheers -ben I've also added tests for SHA256 similar to the snippets above.
