void

DoSetKey

(

const TDesC8 &

aKey

)

[protected, virtual]

Initialises the three key schedule arrays from the specified key.

const TDesC8 & aKey

The key to be used for encryption. The key length must be K3DESKeySize = 24 bytes.

NewL

(

const TDesC8 &

aKey

)

[static]

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()

const TDesC8 & aKey

The key to be used for encryption. The key length must be K3DESKeySize = 24 bytes.

NewLC

(

const TDesC8 &

aKey

)

[static]

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()

const TDesC8 & aKey

The key to be used for encryption. The key length must be K3DESKeySize = 24 bytes.
