Method Summary

Modifier and Type	Method and Description
public int	Returns: the length of the padding padLength(int the length of the data to pad len) Determines how long the padding will be for a given input length.
public void	padWithLen(byte[] the input buffer with the data to pad in, int the offset in `in` where the padding bytes are appended off, int the number of padding bytes to add len) Adds the given number of padding bytes to the data input.
public int	Returns: the index where the padding starts, or -1 if the input is not properly padded unpad(byte[] the buffer with the data and their padding in, int the offset in `in` where the data starts off, int the length of the data and their padding len) Returns the index where padding starts.

Method Detail

padLength	back to summary
public int padLength(int len) Determines how long the padding will be for a given input length. Parameters len:int the length of the data to pad Returns:int the length of the padding

padLength

back to summary

public int padLength(int len)

Determines how long the padding will be for a given input length.

Parameters

len:int: the length of the data to pad

Returns:int

the length of the padding

padWithLen back to summary

padWithLen	back to summary
public void padWithLen(byte[] in, int off, int len) throws ShortBufferException 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. Parameters in:byte[] the input buffer with the data to pad off:int the offset in `in` where the padding bytes are appended len:int the number of padding bytes to add Exceptions ShortBufferException: if `in` is too small to hold the padding bytes

public void padWithLen(byte[] in, int off, int len) throws ShortBufferException

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.

Parameters

in:byte[]: the input buffer with the data to pad
off:int: the offset in in where the padding bytes are appended
len:int: the number of padding bytes to add

Exceptions

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

unpad back to summary

unpad	back to summary
public int unpad(byte[] in, int off, int len) Returns the index where padding starts. Given a buffer with data and their padding, this method returns the index where the padding starts. Parameters in:byte[] the buffer with the data and their padding off:int the offset in `in` where the data starts len:int the length of the data and their padding Returns:int the index where the padding starts, or -1 if the input is not properly padded

public int unpad(byte[] in, int off, int len)

Returns the index where padding starts.

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

Parameters

in:byte[]: the buffer with the data and their padding
off:int: the offset in in where the data starts
len:int: the length of the data and their padding

Returns:int

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