Description

This API is used to wrap the data using AES-KW in single step without initializing context.

Parameters


No.	Argument Type	Argument Name	Type	Description
1	crypto_HandlerType_E	handlerType_en	Input	Enum for crypto operation handler i.e., SW, HW
2	uint8_t*	ptr_inputData	Input	Input data to wrap
3	uint32_t	inputLen	Input	Input length of plain data in bytes
4	uint8_t*	ptr_outData	Output	Pointer to store cipher text as output
5	uint8_t*	ptr_key	Input	Key for the Symmetric operation
6	uint32_t	keyLen	Input	Key length for the Symmetric algorithm in bytes
7	uint8_t*	ptr_initVect	Input	Initialization vector
8	uint32_t	sessionID	Input	It defines the session ID, must be more than zero

Returns


Return Type	Description
crypto_Sym_Status_E	Function returns the status of the API.

Example

#define sessionID 1
crypto_Sym_Status_E status;
crypto_HandlerType_E handlerType_en = CRYPTO_HANDLER_HW_INTERNAL;
uint8_t key[16] = {/*data*/};
uint32_t keyLen = sizeof(key);
uint8_t *ptr_initVect = NULL;
uint8_t inputData[64] = {/*data*/};
uint32_t dataLen = sizeof(inputData);
uint8_t outData[64];

status = Crypto_Sym_AesKeyWrapDirect(
    handlerType_en,
    inputData, 
    dataLen, 
    outData, 
    key, 
    keyLen, 
    ptr_initVect,
    sessionID
    );
