Summary

Added support for Ed25519 (ECC_NIST_EDWARDS25519) curve in imported key material specifications

Security assessment

This documents the addition of Ed25519 curve support, a modern cryptographic standard for digital signatures. While it enhances security capabilities, there is no evidence it addresses an existing vulnerability.
