scrypt_derive_native(password: bytes, salt: bytes, n: int, r: int, p: int, length: int) -> bytes

Derive Scrypt key material through explicit compiled Rust support.

Parameters:

• password (bytes) – Secret input bytes.
• salt (bytes) – Caller-selected salt bytes.
• n (int) – Power-of-two CPU/memory cost greater than one.
• r (int) – Block-size cost parameter.
• p (int) – Parallelization cost parameter.
• length (int) – Requested output length.

Returns:

• bytes – Derived key bytes.

Raises:

• RuntimeError – If native Scrypt is unavailable.
• ValueError – If Scrypt parameters are invalid.

This no-fallback variant does not choose safe parameter values or limit the resource cost requested by the caller.
