pub unsafe extern "C" fn Hacl_P256_dh_responder(
    shared_secret: *mut u8,
    their_pubkey: *mut u8,
    private_key: *mut u8
) -> bool

Execute the diffie-hellmann key exchange.

The function returns true for successful creation of an ECDH shared secret and false otherwise.

The outparam shared_secret points to 64 bytes of valid memory, i.e., uint8_t[64]. The argument their_pubkey points to 64 bytes of valid memory, i.e., uint8_t[64]. The argument private_key points to 32 bytes of valid memory, i.e., uint8_t[32].

The function also checks whether private_key and their_pubkey are valid.
