void
|
DoSetKey
|
(

const
TDesC8
&
|
aKey
|
)
|
[protected, pure virtual]
|
Initialises the three key schedule arrays from the specified key.
Parameters
|
const
TDesC8
& aKey
|
The key to be used for encryption. The key length must be K3DESKeySize = 24 bytes.
|
KeySize()
|
TInt
|
KeySize
|
(
|
)
|
const [virtual]
|
Gets the key size in bits.
Reset()
Resets the transformation back to its original state. Clears all its buffers.
Transform(TDes8 &)
|
void
|
Transform
|
(
|
TDes8
&
|
aBlock
|
)
|
[virtual]
|
Transforms the supplied block, returning the new value using the same parameter. aBlock.Size() must be the same length as
BlockSize()
.
Parameters
|
TDes8
& aBlock
|
On input, the data to be transformed; on return, the data after transformation.
