SSL Certificate Check API

Connects to a host over TLS and reports whether its certificate is trusted, who issued it, the names it covers, when it expires (with days remaining), serial number, signature and key type, plus the TLS version and cipher the server negotiated. Invalid certificates are still decoded and the reason is explained in plain English.
