Member Functions Documentation
NewL(const TDesC8 &, TInt)
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 encryption. The key length must fall between 1 and KRC2MaxKeySizeBytes (=128) bytes inclusive. |
| TInt aEffectiveKeyLenBits =
KSSLCompatibilityBits
| Effective key length bits (defaults KSSLCompatibilityBits = 1024). |
NewLC(const TDesC8 &, TInt)
Creates an instance of this class and leaves it on the cleanup stack.
-
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 encryption. The key length must fall between 1 and KRC2MaxKeySizeBytes (=128) bytes inclusive. |
| TInt aEffectiveKeyLenBits =
KSSLCompatibilityBits
| Effective key length bits (defaults KSSLCompatibilityBits = 1024). |
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. |
