I'm running Leap 15.4 using KDE and KMail for my email (old habits are hard to break). I received and verified a notice from my ISP that they will be requiring TLS 1.3 (but will accept 1.2) starting September 1. How do I determine what version of TLS is in use on my system, and if it is not an acceptable one, how do I upgrade it? Thank you, Mark -- At a towing company: "We don't charge an arm and a leg.

Hi, TLS is not a command. It's what is used to encrypt data transmission on networks. The support for it is built into programs which establish secure data transmission - such as web and email browsers and servers. What service is your ISP referring to? If its an email service you use with them, they likely mean it for IMAPS and SMTPS, which would mean your email client needs to support it. Most modern email clients support TLS version 1.3 - it's a very common implementation nowadays. Same goes for web browsers. Best, Georg On 8/26/22 22:33, Mark Neidorff wrote:

Thank you. On different machines I use IMAPS and SMTPS, so fingers crossed. Mark On Friday, August 26, 2022 4:41:04 PM EDT Georg Pfuetzenreuter wrote:

There are several libraries implementing SSL/TLS and it depends on what library KMail is using. OpenSSL and GnuTLS (two most common) support TLS 1.3 since a long time. It seems that kmail binary loads both OpenSSL and GnuTLS libraries so I assume it is using one of those (do not know how to selects specific implementation).
