UseTLS disable older tls version


how to disable TLS 1.0 and 1.1 when using NetworkServer with UseTLS=true?
I want only 1.2 (and, maybe, 1.3).

Would it also be possible to select which ciphers are allowed?


Unfortunately atm we don’t expose such API. By default TLS 1.1, TLS 1.2 and TLS 1.3 (where available) are enabled.

I’ll log an issue to expose API that would allow to set allowed TLS protocols.
Also we’ll investigate if it is possible to allow to modify list of used ciphers on SSL data stream used internally.
