Pull request overview
This PR fixes the ECX key-management security-bits calculation so the provider reports correct EVP_PKEY_get_security_bits() values for X25519 (128) and X448 (224), and adds a unit test to prevent regressions.
Changes:
- Adjust
wp_ecx_get_security_bits()thresholds to correctly map X448 and X25519 bit sizes to their security-bit strengths. - Add a new ECX unit test that generates X25519/X448 keys with OpenSSL and wolfProvider and compares reported security bits.
- Register the new test in the unit test declarations and test-case table.
