Function Documentation

fr_hmac_sha1()

int fr_hmac_sha1	(	uint8_t	digest[static SHA1_DIGEST_LENGTH],
		uint8_t const *	in,
		size_t	inlen,
		uint8_t const *	key,
		size_t	key_len
	)

Calculate HMAC using internal SHA1 implementation.

Parameters

digest	Caller digest to be filled in.
in	Pointer to data stream.
inlen	length of data stream.
key	Pointer to authentication key.
key_len	Length of authentication key.

Returns

• 0 on success.
• -1 on error.
