PqHybridProfile enum

Hash digest engine + security-profile pairing used by PqForgeCombiner.

Fixing the digest fixes the HKDF extract/expand boundary so the combiner stays inside the cryptographic strength of the negotiated KEM. The mapping is intentionally closed (only vetted SHA-2 members) so a caller can never downgrade the KDF to a weak or non-collision-resistant hash.

Values

balanced → const PqHybridProfile

Balanced profile — SHA-256 HKDF. Pairs with ML-KEM-768 (NIST level 3).

const PqHybridProfile('SHA-256', 32)

heavy → const PqHybridProfile

Heavy / high-security profile — SHA-512 HKDF. Pairs with ML-KEM-1024 (NIST level 5).

const PqHybridProfile('SHA-512', 64)
