Parameters


No.	Argument Type	Argument Name	Type	Description
1	st_Crypto_Sym_BlockCtx*	ptr_tdesCtx_st	Input	TDES/3DES algorithm context.
2	crypto_HandlerType_E	handlerType_en	Input	Enum for crypto operation handler i.e., SW, HW.
3	crypto_CipherOper_E	cipherOpType_en	Input	Selection cipher operation is encryption or decryption.
4	crypto_Sym_OpModes_E	opMode_en	Input	Select operation mode. i.e., ECB, CBC, or others.
5	uint8_t*	ptr_key	Input	Key for the symmetric operation.
6	uint8_t*	ptr_initVect	Input	Initialization vector. Use NULL when ECB mode.
7	uint32_t	sessionID	Input	It defines the session ID, must be more than zero.

Returns
