EncryptionData(void)

const CPBEncryptionData &

EncryptionData

(

void

)

const [pure virtual]

Gets the parameters allowing one to re-create the object with the same state at another point in the future.

In order to decrypt any information previously encrypted with this object, you must store this encryption data along with it. Failure to do this will result in the permanent loss of the encrypted information.

Parameters

void

MaxCiphertextLength(TInt)

TInt

MaxCiphertextLength

(

TInt

aPlaintextLength

)

const [pure virtual]

Gets the maximum output ciphertext length given a specified input plaintext length.

Parameters

TInt aPlaintextLength

The plaintext length

MaxPlaintextLength(TInt)

TInt

MaxPlaintextLength

(

TInt

aCiphertextLength

)

const [pure virtual]

Gets the maximum output plaintext length given a specified input ciphertext length.

Parameters

TInt aCiphertextLength

The ciphertext length

NewDecryptL(void)

CPBDecryptor *

NewDecryptL

(
