Pull request overview

Adds post-quantum ML-KEM (KEM) and ML-DSA (Dilithium) support to the wolfSSL C# wrapper, enabling consumers to generate/import/export keys and perform encapsulation/decapsulation and signing/verification from managed code.

Changes:

• Expose wolfSSL_UseKeyShare() and add a C# NamedGroup enum for selecting PQ/hybrid TLS key shares.
• Add C# P/Invoke bindings and managed helper APIs for ML-KEM and ML-DSA (Dilithium) operations in wolfCrypt.cs.
• Extend the C# wrapper test app with ML-KEM and ML-DSA exercise tests; enable required build flags in user_settings.h.

Pull request overview

Adds post-quantum ML-KEM (key encapsulation) and ML-DSA / Dilithium (signatures) support to the C# wrapper layer, including TLS NamedGroup IDs for hybrid/PQ key shares, and enables the required wolfSSL build flags for the C# wrapper build.

Changes:

• Add wolfSSL_UseKeyShare() P/Invoke plus a NamedGroup enum for (hybrid) PQ key share selection in the C# wolfSSL wrapper.
• Add ML-KEM and ML-DSA (Dilithium) P/Invoke bindings and higher-level convenience wrappers in wolfCrypt.cs.
• Add C# wrapper tests for ML-KEM encapsulation/decapsulation and ML-DSA key export/import + sign/verify, and enable required build macros in user_settings.h.

Pull request overview

Adds post-quantum (PQC) ML-KEM and ML-DSA support to the wolfSSL C# wrapper, aligning the wrapper with upstream functionality (referenced from PR #9040) and enabling PQC usage in both TLS (key shares) and wolfCrypt APIs.

Changes:

• Add wolfSSL_UseKeyShare() P/Invoke + a NamedGroup enum to support ML-KEM (and other) TLS key share selection from C#.
• Add ML-KEM and Dilithium (ML-DSA) P/Invokes and managed wrapper APIs to wolfCrypt.cs.
• Add C# wrapper test coverage for ML-KEM encaps/decaps and ML-DSA sign/verify; enable needed features in user_settings.h.

Pull request overview

Adds post-quantum algorithm support to the C# wrapper layer by exposing ML-KEM (key encapsulation) and ML-DSA (Dilithium signing) APIs, plus TLS 1.3 key-share selection for PQ/hybrid groups. This aligns the wrapper with the underlying wolfSSL/wolfCrypt capabilities referenced by PR #9040.

Changes:

• Expose wolfSSL_UseKeyShare() via a new UseKeyShare() wrapper and a NamedGroup enum in wolfSSL.cs.
• Add ML-KEM key management/encode/decode/encapsulate/decapsulate APIs and Dilithium (ML-DSA) key/sign/verify APIs in wolfCrypt.cs.
• Add C# wrapper tests for ML-KEM shared secret agreement and ML-DSA sign/verify, and enable the required build flags in user_settings.h.
