question: protected void engineSetPadding ( String paddingScheme ) throws NoSuchPaddingException { if ( ( paddingScheme != null ) && ( ! paddingScheme . equalsIgnoreCase ( "PKCS5Padding" ) ) ) { throw new NoSuchPaddingException ( "Invalid padding scheme: " + paddingScheme ) ; } }
target:  Sets the padding mechanism of this cipher. This algorithm only uses PKCS #5 padding.
