Method Detail

pad

public void pad(ByteArrayOutputStream in)

Adds the given number of padding bytes to the data input. The value of the padding bytes is determined by the specific padding mechanism that implements this interface.

Specified by:

pad in interface IPadding

Parameters:

in - the input buffer with the data to pad

off - the offset in in where the padding bytes are appended

len - the number of padding bytes to add

Throws:

ShortBufferException - if in is too small to hold the padding bytes

unpad

public byte[] unpad(byte[] in)

Returns the index where the padding starts.

Given a buffer with padded data, this method returns the index where the padding starts.

Specified by:

unpad in interface IPadding

Parameters:

in - the buffer with the padded data

off - the offset in in where the padded data starts

len - the length of the padded data

Returns:

the index where the padding starts, or -1 if the input is not properly padded
