- - ### Constructor Detail

    - #### AESWrapEngine

          public AESWrapEngine()

      Create a regular AESWrapEngine specifying the encrypt for wrapping, decrypt for unwrapping.

    - #### AESWrapEngine

          public AESWrapEngine(boolean useReverseDirection)

      Create an AESWrapEngine where the underlying cipher is set to decrypt for wrapping, encrypt for unwrapping.
      Parameters:
        `useReverseDirection` - true if underlying cipher should be used in decryption mode, false otherwise.
