js实现AES加密解密，简易又全面

常规是直接安装CryptoJS库，但为了减少项目体积，使用这简单的20k文件就ok
一览：

代码中使用的是Pkcs7，但我需要的填充方式是ZeroPadding
所以稍微有修改：

  q = (p.pad = {}).ZeroPadding = {
      pad: function (data, blockSize) {
        var blockSizeBytes = blockSize * 4
        data.clamp()
        data.sigBytes += blockSizeBytes - ((data.sigBytes % blockSizeBytes) || blockSizeBytes)
      },
	    unpad: function (data) {
	        // Shortcut
	        var dataWords = data.words;

	        // Unpad
	        var i = data.sigBytes - 1;
	        for (var i = data.sigBytes - 1; i >= 0; i--) {
	            if (((dataWords[i >>> 2] >>> (24 - (i % 4) * 8)) & 255)) {
	                data.sigBytes = i + 1;
	                break;
	            }
	        }
	    }
    }

完整代码如下：
