Function Documentation

get_auth_key_from_cell()

STATIC void get_auth_key_from_cell	(	ed25519_public_key_t *	auth_key_out,
		unsigned int	cell_type,
		const void *	cell
	)

Extract the authentication key from an ESTABLISH_INTRO or INTRODUCE1 using the given cell_type from cell and place it in auth_key_out.

verify_establish_intro_cell()

STATIC int verify_establish_intro_cell	(	const trn_cell_establish_intro_t *	cell,
		const uint8_t *	circuit_key_material,
		size_t	circuit_key_material_len
	)

We received an ESTABLISH_INTRO cell. Verify its signature and MAC, given circuit_key_material. Return 0 on success else -1 on error.
