Research direction

First verify whether Windows NCrypt supports Composite ML-DSA, using the linked Microsoft Security Blog as context. Then inspect the existing CNG algorithm and X509 handling areas for the mentioned CompositeMLDsaCng and CngAlgorithm impacts. Done means support is added across the required CNG and X509 surfaces once the platform capability exists.

Description

area-System.Security

When/if Windows adds support for Composite ML-DSA to NCrypt (implied by https://techcommunity.microsoft.com/blog/microsoft-security-blog/post-quantum-cryptography-comes-to-windows-insiders-and-linux/4413803), we should add support in the form of CompositeMLDsaCng, and associated impact (such as CngAlgorithm, and X509 handling)
