+### AWS SDK for .NET

+On Linux, AWS SDK for .NET relies on system libssl/libcrypto. To use PQ TLS, use this SDK on an operating system distribution that has at least OpenSSL 3.5 installed. On Windows and MacOS, PQ TLS is available starting in [.NET 10](https://devblogs.microsoft.com/dotnet/post-quantum-cryptography-in-dotnet/) and [Windows 11](https://techcommunity.microsoft.com/blog/microsoft-security-blog/post-quantum-cryptography-apis-now-generally-available-on-microsoft-platforms/4469093). On MacOS, TLS 1.3 support (a prerequisite for PQ TLS) can be enabled by opting-in to Apple's Network.framework as described [here](https://learn.microsoft.com/en-us/dotnet/core/whats-new/dotnet-10/libraries#tls-13-for-macos-client). Assuming a minimum .NET version of 10, PQ TLS should then be enabled.
