CPBEncryptor Class Reference

class CPBEncryptor : public CBase

Abstract class defining the interface required to allow the actual transformation of plaintext to ciphertext.

Generally this class' descendants are constructed using the functions CPBEncryptElement::NewEncryptLC() or CPBEncryptSet::NewEncryptLC().

TInt

MaxFinalOutputLength

(

aMaxInputLength

)

const [pure virtual]

Gets the maximum length of the output resulting from calling ProcessFinalL() with a given input length.

TUint aMaxInputLength

The maximum input length in bytes.

TInt

MaxOutputLength

(

aMaxInputLength

)

const [pure virtual]

Gets the maximum length of the output resulting from calling Process() with a given input length.

TUint aMaxInputLength

The maximum input length in bytes.

Transforms aInput into its encrypted form, aOutput.

See the Cryptography api-guide documentation for an explanation of how buffering of data supplied to this function is handled.

const TDesC8 & aInput	The plaintext.
TDes8 & aOutput	On return, the ciphertext.

Transforms aInput into its encrypted form, aOutput, and applies a padding scheme to ensure a block aligned result.

See the Cryptography api-guide documentation for an explanation of how buffering of data supplied to this function is handled.

const TDesC8 & aInput	The plaintext.
TDes8 & aOutput	On return, the ciphertext.
