I am looking for a way to enable TLSv1.3 support on a .Net Application running on Windows Server 2012. While I knew .Net relied on the OS for portions of the TLS stack, I didn't realize that this made it so TLSv1.3 was largely unsupported for most…
I have the following cipher suites set trough policy:
As per this list (https://learn.microsoft.com/en-us/windows/win32/secauthn/tls-cipher-suites-in-windows-server-2022) I had expected the two "unresolved" ciphers to map to 771, TLS1.2.
Any advice…

How can I request a key update on a TLS v1.3 connection implemented with Win32's SChannel?
In other words, what is the Win32 function that provides similar functionality as SSL_key_update() in OpenSSL?
I did not find any useful information in the…
I have a simple challenge as I'm working on a multi-platform project where I have a server with TLS 1.2 and a client certificate that is required to authenticate any REST API calls. This works fine on Linux, in WSL and in Docker/Linux. But not on…
Does SChannel support TLS 1.3 ? I need help with regard to example client/server programs in C/C++ for implementing TLS 1.3 using SChannel.
I found SChannel.h defines SP_PROT_TLS1_3_CLIENT as 0x00002000, etc.
But the grbitEnabledProtocols field of…
