CPaddingNone Class Reference
|
class CPaddingNone : public CPadding
|
This concrete subclass of
CPadding
appends no padding.
aOutput will be a copy of aInput after any call to
PadL()
or
UnPadL()
.

const [virtual]
|
Gets the size of the aOutput buffer, in a call to
PadL()
, must be in order to accommodate a block size of
BlockSize()
and an input size of aInputBytes.
Note:
By default, this function returns the output of
BlockSize()
. If a derived padding system outputs more than a single block of padding, one must override this function and return the appropriate value.
Parameters
|
TInt
aInputBytes
|
The amount of data to be padded out in bytes.
|
MinPaddingLength(void)
|
TInt
|
MinPaddingLength

(
|
void
|
|
)
|
const [virtual]
|
Gets the smallest number of bytes that
PadL()
will ever add to aInput in order to get a valid block aligned aOutput.
For example, in SSLv3 padding, if the block size is 8 and aInput is 7 bytes, it will append 1 byte of padding. For SSLv3 padding, this is the smallest amount possible as an 8 byte input will add another block size (8 more bytes) of padded data.
NewLC(TInt)
Creates a new
CPaddingNone
object and leaves a pointer to it on the cleanup stack.

|

)

[virtual]
|
Removes padding from aInput and appends unpadded result to aOutput.
Parameters
|
const
TDesC8
& aInput
|
Data to be unpadded.
|
|
TDes8
& aOutput
|
On return, the unpadded data.
