Function Documentation

void wiced_sha2_hmac	(	const unsigned char *	key,
		uint32_t	keylen,
		const unsigned char *	input,
		uint32_t	ilen,
		unsigned char	output[32],
		int32_t	is224
	)

Calculated HMAC-SHA.

Output = HMAC-SHA-256(224)( hmac key, input buffer )

Parameters

key	- HMAC secret key
keylen	- length of the HMAC key
input	- buffer holding the data
ilen	- length of the input data
output	- HMAC-SHA-224/256 result
is224	- 0 = use SHA256, 1 = use SHA224
