How is the TLS version selected between client and server Check the bold text in the again RFC 5246, Appendix E: A TLS 1.2 client who wishes to negotiate with such older servers will send a normal TLS 1.2 ClientHello, containing { 3, 3 } (TLS 1.2) in ClientHello.client_version. If the server does not support this version, it will respond with a ServerHello containing an older version number. Check if Your Website Supports TLS 1.2 - 1-Minute Tutorial Alternatively, there is a website you can use that will check your SSL certificate and tell you which protocols it supports. This will show you which TLS versions are enabled, but not whether HTTP/1.1 is available. Go to the DigiCert SSLTools website. Click “Check SSL/TLS. Enter in your website address and click “Check”.

Check and Adjust the TLS/SSL Protocol Version - SAP To check the TLS version in your system: Call transaction RZ11 and enter ssl/client_ciphersuites. Check that the value of parameter ssl/client_ciphersuites is set to 150:PFS:HIGH::EC_P256:EC_HIGH (unless you have an exceptional use case, in which case refer to the values in SAP Note 510007 ). c# - How do you check the Negotiated TLS Handshake from If I have a dozen endpoints, and my WebAPI Service is configured for TLS 1.1 and TLS 1.2, how do I check each incoming endpoint request to see which version was negotiated?. So if a consumer of my endpoints currently only supports TLS 1.0 and TLS 1.1, they'll (obviously?) negotiate a TLS 1.1 handshake. But if a different consumer supports TLS 1.2 and TLS 1.3, they'll (obviously?) negotiate a How is the TLS version selected between client and server
