 MLDsaKeyGenerationParameters Key generation parameters for ML-DSA (FIPS 204). Carries the used to draw the seed material together with the chosen selector. Strength is implied by the parameter set, so the base strength field is left at zero.

 MLDsaParameters Algorithm parameter set identifiers for ML-DSA (Module-Lattice-Based Digital Signature Algorithm) as specified in FIPS 204.

 MLDsaParameterSet The three ML-DSA parameter sets defined by FIPS 204, identified by the matrix dimensions (k, ℓ) embedded in the name. Each entry binds the textual name to the engine mode that produces the standardised public-key, private-key and signature sizes.

 MLDsaPrivateKeyParameters ML-DSA private key (FIPS 204). The expanded key holds (ρ, K, tr, s₁, s₂, t₀) derived from a 32-byte seed; the corresponding t₁ half of the public key is cached for fast public-key recovery. A key built from a seed retains the seed so it can be re-encoded in the seed format.

 MLDsaPublicKeyParameters An ML-DSA public (verification) key, as specified in FIPS 204.

 MLKemKeyGenerationParameters Key generation parameters for ML-KEM (FIPS 203). Carries the used to draw the seed material together with the chosen selector. Strength is implied by the parameter set, so the base strength field is left at zero.

 MLKemParameters Algorithm parameter set identifiers for ML-KEM (Module-Lattice-Based Key-Encapsulation Mechanism) as specified in FIPS 203.

 MLKemParameterSet The three ML-KEM parameter sets defined by FIPS 203, distinguished by the module-lattice rank k. Each entry binds the textual name to a configured engine that produces the standardised ciphertext and shared-secret sizes.

 MLKemPrivateKeyParameters An ML-KEM private (decapsulation) key, as specified in FIPS 203.

 MLKemPublicKeyParameters An ML-KEM public (encapsulation) key, represented by the raw byte encoding defined in FIPS 203.

 SlhDsaKeyGenerationParameters Key generation parameters for SLH-DSA (FIPS 205). Carries the used to draw the seed material together with the chosen selector. Strength is implied by the parameter set, so the base strength field is left at zero.

 SlhDsaParameters Parameter selector for SLH-DSA, the stateless hash-based signature scheme standardised by NIST in FIPS 205. Each instance binds a parameter set (security level, fast/small variant, hash family) to its NIST OID; the WITH variants additionally pre-hash the message with the indicated digest (HashSLH-DSA, FIPS 205 §10.2).

 SlhDsaParameterSet The 12 SLH-DSA tree parameter sets defined by FIPS 205, identifying the WOTS+ (w), hypertree (d, h) and FORS (a, k) shape together with the security parameter n and the underlying hash family (SHA-2 or SHAKE-256).
