padding

I'm trying to to port a Java (simple) encryption algorythm to Node JS. I will need to be able to decrypt/encrypt stuff encrypted/decrypted from the Java side. I'm stuck at the very beginning, the initialization of the cipher. In Java, I get the key with SecretKeySpec , and the Initialization Vector with IvParameterSpec : public CryptStuff(String password) throws zillion_exceptions { if (password==null) throw new InvalidKeyException("No encryption password is set!"); key = new SecretKeySpec(password.getBytes("UTF-8"), "AES"); cipher = Cipher.getInstance("AES/CBC/PKCS5Padding"); ivSpec=new

Almost all things work fine, except 9-Patch PNGs. final Bitmap bubble = getFromTheme("bubble"); if (bubble == null) return null; final byte[] chunk = bubble.getNinePatchChunk(); if (!NinePatch.isNinePatchChunk(chunk)) return null; NinePatchDrawable d = new NinePatchDrawable(getResources(), bubble, chunk, new Rect(), null); v.setBackgroundDrawable(d); d = null; System.gc(); getFromTheme() loads the Bitmap from the SD card. The 9-Patch PNGs are already compiled, that means they include the required chunk. The way

The problem is that this overlayed div will take priority of any mouse events, so it renders the interactive google map below useless. There must be a way I can make the overlayed div ignore mouse events, letting the div below get them. (please, please!) Or, is there another way to do it? here's the code being output: <div id = "pageWrapper" style = " display : block ; " > <div class = "page
