    Are you asking how to determine which version of TLS/SSL a particular connection to a website is using? Or that a particular server supports? You seem to have a good handle that you need to use TLS/SSL in order to secure traffic against eavesdropping/manipulation. Jun 13, 2017 at 14:58
  • @Xander: the chrome instructions are obsolete, which means that answer doesn't help most users... This is a good question i thought at first i knew the snappy answer to.

  • @ISMSDEV: i don't have a "Your connection to this site is private." part on the single-click padlock popup or the word "details", on this site. a valid answer would be of use to many. if a site doesn't have a cert, that's easy, but how to get cert details? It's not in the "Learn More" link, nor the "Site Settings". WTF?
