Generates an IND-CPA key pair deterministically.

Parameters

[out]	pk	Public key output buffer.
[in]	pk_len	Size of the public key buffer in bytes.
[out]	sk	Secret key output buffer.
[in]	sk_len	Size of the secret key buffer in bytes.
[in]	coins	Random coins of 2 * MLKEM_SYMBYTES bytes.
[in]	p	Pointer to the ML-KEM parameter set.

Returns

CX_OK on success, error code otherwise.
