Function Documentation

int ff_dh_compute_shared_secret_key	(	FF_DH *	dh,
		const uint8_t *	pub_key,
		int	pub_key_len,
		uint8_t *	secret_key
	)

Compute the shared secret key from the private FF_DH value and the other party's public value.

Parameters

dh	a Diffie-Hellmann context, containing the private key
pub_key	the buffer containing the public key
pub_key_len	the length of the buffer
secret_key	the buffer where the secret key is written

Returns

length of the shared secret key on success, negative value otherwise
