Function Documentation

eckcdsa_pub_key_validation()

int8_t eckcdsa_pub_key_validation	(	ec_point *	pub_key,
		ec_curve *	curve
	)

Verify that the public key is valid (id est check taht pub_key belongs to the curve, that pub_key is not the neutral element and that pub_key is of ordre n)

Parameters

hash	H(m) where H is a cryptographic hash function and m the message to sign. Must be written under hexadecimal form. ex: 64 hexadecimal characters for sha256.
pub_key	Public key
curve	Elliptic curve

Returns

1 on success, 0 on failure
