crypto_Sym_Status_E Crypto_Sym_Camellia_Cipher(
st_Crypto_Sym_BlockCtx *ptr_camCtx_st,
uint8_t *ptr_inputData,
uint32_t dataLen,
uint8_t *ptr_outData
);
Description
This API performs Camellia encryption or decryption for different operation modes.
Initialize context by calling Crypto_Sym_Camellia_Init function before calling this
API.
Parameters
No. | Argument Type | Argument Name | Type | Description |
---|
1 | st_Crypto_Sym_BlockCtx* | ptr_camCtx_st | Input | Camellia
algorithm context |
2 | uint8_t* | ptr_inputData | Input | Input data to
encrypt or decrypt |
3 | uint32_t | dataLen | Input | Input length
of plain data or cipher data in bytes |
4 | uint8_t* | ptr_outData | Output | Pointer to
store cipher text/plain text as output |
Returns
Return Type | Description |
---|
crypto_Sym_Status_E | Function
returns the status of the API. |
Prerequisites
- To use the HW handler, the
algorithm must be enabled in Crypto v4 in MPLAB® Code Configurator.
- To use the SW handler, the
algorithm must be enabled in wolfCrypt, and linked to Crypto V4 in MPLAB® Code
Configurator.
- Crypto_Sym_Camellia_Init must be called prior to calling
Crypto_Sym_Camellia_Cipher.
