Convert algorithm dictionaries on the original receiver, with name read once. Validate normalized parameters in their operation steps after the method-level key checks and generation usage checks. This also makes Argon2 validation use converted parallelism and keeps later dictionary conversion errors ahead of semantic parameter errors.

Require cSHAKE and KMAC output lengths and KMAC key lengths to be multiples of 8 bits. KMAC keys must be at least 32 bits. Share these restrictions between operations and supports. Use OpenSSL's KMAC provider for all supported inputs and its cSHAKE implementation for non-empty function names or customization strings. Keep using SHAKE when both cSHAKE parameters are empty. Remove the custom Keccak framing, partial-bit handling, and short-key fallback. Document the OpenSSL 4.0 requirement for non-empty cSHAKE parameters and reject customization strings containing null bytes. Keep the documented 512-byte customization limit and let backend failures reach callers.
