ldns_sha1()

unsigned char * ldns_sha1	(	const unsigned char *	data,
		unsigned int	data_len,
		unsigned char *	digest
	)

Convenience function to digest a fixed block of data at once.

Parameters

[in]	data	the data to digest
[in]	data_len	the length of data in bytes
[out]	digest	the length of data in bytes This pointer MUST have LDNS_SHA1_DIGEST_LENGTH bytes available

Returns

the SHA1 digest of the given data
