public PKCS5Padding(int blockSize)
```
- 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
