Function keygen_internal 

pub fn keygen_internal<P: Params>(
    d: &[u8; 32],
    z: &[u8; 32],
) -> (Vec<u8>, Vec<u8>)

Deterministic ML-KEM key generation (Algorithm 16).

Generates an encapsulation/decapsulation key pair from explicit seeds. The decapsulation key is structured as dk_pke || ek || H(ek) || z.

Arguments

• d - 32-byte seed passed to kpke::keygen for K-PKE key generation.
• z - 32-byte implicit rejection value embedded in the decapsulation key.

Returns

A tuple (ek, dk) of byte vectors.
