CBlockTransformation Class Reference

class CBlockTransformation : public CBase

Abstract base class defining the interface to block transformation schemes.

Block transformation schemes process a fixed-size block of input to return a block of output the same size.

Member Functions Documentation

BlockSize()

TInt BlockSize()const [pure virtual]

Gets the block size in bytes.

GetExtension(TUint, TAny *&, TAny *)

TInt GetExtension(TUintaExtensionId,
TAny *&a0,
TAny *a1
)

Used to retrieve the extended interfaces by id. For Crypto SPI internal use only.

Parameters

TUint aExtensionId
TAny *& a0
TAny * a1

KeySize()

TInt KeySize()const [pure virtual]

Gets the key size in bits.

Reset()

voidReset()[pure virtual]

Resets the transformation back to its original state. Clears all its buffers.

Transform(TDes8 &)

voidTransform(TDes8 &aBlock)[pure virtual]

Transforms the supplied block, returning the new value using the same parameter. aBlock.Size() must be the same length as BlockSize().

Parameters

TDes8 & aBlockOn input, the data to be transformed; on return, the data after transformation.
