Member Function Documentation
TECipher * instance()
The instance method retrieves the TECipher instance.
void init(uint64_t keyhandle, Operation operation, Mode mode=DEFAULT)=0
The init method initializes a TECipher object.
Parameters
| Parameter | Description |
|---|---|
keyhandle | An integer representing the key handle from TEKey::createKeyHandle() |
operation | An Operation object representing the operation. |
mode | A Mode object representing the mode of operation. |
void update(const Data &in, Data &out)=0
The update method updates TECipher with data.
Parameters
| Parameter | Description |
|---|---|
in | - input data |
out | - output buffer |
void finalize(Data &out, bool append=false)=0
The finalize method finalizes the output buffer.
Parameters
| Parameter | Description |
|---|---|
out | - output buffer |
append | - indicates that processed data will be appended to existing |
void process(const Data &in, Data &out)=0
The process method proccess the data.
Parameters
| Parameter | Description |

Parameters
| Parameter | Description |
|---|---|
in | - input data pointer, NULL is acceptable for final block |
insize | - size of input data |
out | - output data pointer, buffer must be enough to hold processed data |
finalize | - indicates last block |
Data iv() const =0
The iv method retrieves the IV.
return current IV /Counter
