The former at least should handle TLS as well as SSL. Yes, but from skimming the code and a couple comments in other email, it looks like negotiation of TLS at any time other than connection establishment is done using SIGALRM to gnutls, which only starttls.el seems to do, and there was a report that it's not working for someone on Windows. I have no idea whether openssl supports something like that. And if a protocol does any special wrapping or encoding of the TLS-encoded data, I'm guessing it's not going to work well... Ken
