Function Documentation

HAL_StatusTypeDef HAL_CRYPEx_AESCCM_GenerateAuthTAG	(	CRYP_HandleTypeDef *	hcryp,
		uint32_t *	AuthTag,
		uint32_t	Timeout
	)

AES CCM Authentication TAG generation.

Parameters:

hcryp,:	pointer to a CRYP_HandleTypeDef structure that contains the configuration information for CRYP module
AuthTag,:	Pointer to the authentication buffer the AuthTag generated here is 128bits length, if the TAG length is less than 128bits, user should consider only the valid part of AuthTag buffer which correspond exactly to TAG length.
Timeout,:	Timeout duration

Return values:
