Creates an instance of this class.

leave: KErrWeakKey If the key is a weak one, the function leaves having previously cleaned up any previously allocated memory.

leave: KErrKeyNotWeakEnough If the key size is larger than that allowed by the cipher strength restrictions of the crypto library. See TCrypto::IsSymmetricWeakEnoughL()

const TDesC8 & aKey	The key to be used for encryption. The key length must be KDESKeySize = 8 bytes.
TBool aCheckWeakKey = ETrue	Boolean determining whether to check the key against a set of known weak key values. Defaults to ETrue.

const TDesC8 & aKey	The key to be used for encryption. The key length must be KDESKeySize = 8 bytes.
TBool aCheckWeakKey = ETrue	Boolean determining whether to check the resultant key against a set of known weak key values. Defaults to ETrue.
