我使用初始化矢量和填充来实现AES 128位加密，如下面的代码所示。我碰巧正在使用ColdFusion，但我认为这并不重要。加密的结果显示了一些重复的模式，这是我本来不会想到的，但是再次，我不知道为此正确输出的特征。我是否正在正确执行初始化向量和填充？

To encrypt this, for example:
    "String1"
Prefix the string with an Initialization Vector of 16 random characters,
plus enough padding ("000000001") to make the entire string a multiple of 16 characters (32 characters, here)
    "HoMoz4yT0+WAU7CX000000001String1"
Now encrypt the string to this (64 characters):
    "Bn0k3q9aGJt91nWNA0xun6va8t8+OiJVmCqv0RzUzPWFyT4jUMzZ56pG5uFt6bGG"
