int ECDSA_do_verify	(	const unsigned char *	dgst,
		int	dgst_len,
		const ECDSA_SIG *	sig,
		EC_KEY *	eckey
	)

ECDSA_do_verify verifies that the supplied signature is a valid ECDSA signature of the supplied hash value using the supplied public key.

Parámetros:

dgst	pointer to the hash value
dgst_len	length of the hash value
sig	pointer to the ECDSA_SIG structure
eckey	pointer to the EC_KEY object containing a public EC key

Devuelve:

1 if the signature is valid, 0 if the signature is invalid and -1 on error

int ECDSA_verify	(	int	type,
		const unsigned char *	dgst,
		int	dgstlen,
		const unsigned char *	sig,
		int	siglen,
		EC_KEY *	eckey
	)

ECDSA_verify verifies that the given signature is valid ECDSA signature of the supplied hash value using the specified public key.

Parámetros:

type	this parameter is ignored
dgst	pointer to the hash value
dgstlen	length of the hash value
sig	pointer to the DER encoded signature
siglen	length of the DER encoded signature
eckey	pointer to the EC_KEY object containing a public EC key

Devuelve:

1 if the signature is valid, 0 if the signature is invalid and -1 on error
