Pull Request Overview
This PR centralizes RSA-384 support detection across different RSA provider implementations by introducing a new PlatformSupport.IsRSA384Supported property. The change eliminates duplicated platform detection logic and provides a unified approach for determining RSA-384 support.
Key changes:
- Added centralized RSA-384 support detection in
PlatformSupportclass - Replaced provider-specific RSA-384 support checks with calls to the centralized property
- Removed duplicated platform detection code from individual RSA provider classes

Boo. This would backport cleanly if the patch was squashed. |
