|
const [virtual]
|
Gets the block size in bytes.
NewL(const TDesC8 &)
Creates an instance of this class.

leave
-
KErrKeyNotWeakEnough If the key size is larger than that allowed by the cipher strength restrictions of the crypto library. See
TCrypto::IsSymmetricWeakEnoughL()
Parameters
|
const
TDesC8
& aKey
|
The key to be used for decryption. The key length must be either KAESKeySize128 (=16), KAESKeySize192 (=24) or KAESKeySize256 (=32) bytes.
|
NewLC(const TDesC8 &)
Creates an instance of this class and leaves it on the cleanup stack.

-
KErrKeyNotWeakEnough If the key size is larger than that allowed by the cipher strength restrictions of the crypto library. See

Parameters
|
const
TDesC8
& aKey
|
The key to be used for decryption. The key length must be either KAESKeySize128 (=16), KAESKeySize192 (=24) or KAESKeySize256 (=32) bytes.

)
|
[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.
