Constructor Detail

### RC2WrapEngine

    public RC2WrapEngine()

Method Detail

### init

    public void init(boolean forWrapping,
                     CipherParameters param)

  Method init

  Specified by:
    `init` in interface `Wrapper`
  Parameters:
    `forWrapping` - true if for wrapping, false for unwrap.
    `param` - parameters for wrap/unwrapping (iv required for unwrap).

### getAlgorithmName

    public java.lang.String getAlgorithmName()

  Method getAlgorithmName

  Specified by:
    `getAlgorithmName` in interface `Wrapper`
  Returns:
    the algorithm name "RC2".

### wrap

    public byte[] wrap(byte[] in,
                       int inOff,
                       int inLen)

  Method wrap

  Specified by:
    `wrap` in interface `Wrapper`
  Parameters:
    `in` - byte array containing the key.
    `inOff` - offset into in array that the key data starts at.
    `inLen` - length of key data.
  Returns:
    the wrapped bytes.

### unwrap

    public byte[] unwrap(byte[] in,
                         int inOff,
                         int inLen)
                  throws InvalidCipherTextException

  Method unwrap

  Specified by:
    `unwrap` in interface `Wrapper`
  Parameters:
    `in` - byte array containing the wrapped key.
    `inOff` - offset into in array that the wrapped key starts at.
    `inLen` - length of wrapped key data.
  Returns:
    the unwrapped bytes.
  Throws:
    `InvalidCipherTextException`
