Is SChannel supported TLS 1.3 for development? RRS feed

  • Question

  • Is SChannel support TLS 1.3 officially?
    As per the windows sdk 10.0.17763.0 include  file SChannel.h defined SP_PROT_TLS1_3_CLIENT 0x00002000.
    But https://docs.microsoft.com/en-us/windows/win32/api/schannel/ns-schannel-schannel_cred#see-also grbitEnabledProtocols not mentioned about TLS1.3. I was unable to find any other internet information to document that SChannel support TLS1.3.

  • Hi,

    Welcome to the MSDN forum.

    I haven't find any information that SChannel supports TLS 1.3 officially. You've asked in this case, and there is a link about the newest released standard TLS 1.3

    Here is the discussion about TLS1.3: https://techcommunity.microsoft.com/t5/Discussions/TLS-1-3/m-p/410501

    But you might want to keep track of the following official Microsoft documentation for any changes in the support:
    https://docs.microsoft.com/en-us/windows/win32/secauthn/protocols-in-tls-ssl--schannel-ssp-

    You can also reach out to the experts in the dedicated IIS forums over here:
