Function Documentation

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

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

Parameters

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

Returns

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
	)

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

Parameters

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	EC_KEY object containing a public EC key

Returns

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