  • Hi 000sipi,
    As offical document says that .NET Core now takes advantage of TLS 1.3 support in OpenSSL 1.1.1, when it's available in a given environment. With TLS 1.3:
    1.Connection times are improved with reduced round trips required between the client and server.
    2.Improved security because of the removal of various obsolete and insecure cryptographic algorithms.
    When available, .NET Core 3.0 uses OpenSSL 1.1.1, OpenSSL 1.1.0, or OpenSSL 1.0.2 on a Linux system. When OpenSSL 1.1.1 is available, both System.Net.Security.SslStream and System.Net.Http.HttpClient types will use TLS 1.3 (assuming both the client and server support TLS 1.3).
    Windows and macOS do not yet support TLS 1.3. .NET Core 3.0 will support TLS 1.3 on these operating systems when support becomes available.
    More details you can refer to this document.
    [What's new in .NET Core 3.0]
    Best Regards,
