Encryption 带c的加密Js#

我正在学习加密和使用加密js我制作了一个js&c版本。 我试图实现的是，JS或c版本将能够解码彼此的消息

为了进行测试，我在JS和C#实例中保持了IV和键，填充和模式相同

我让他们分别对数据进行解密和加密，但我还没有完成的是提供一个加密的JS，以便能够使用c#解码

如果（cipherText==null | | cipherText.Length基本上会遇到编码问题。首先，在一个实现中使用Base64解码解析IV，在另一个实现中使用直接字符编码。Base64字符串看起来也不像Base64字符串

此外，许多库（错误地）允许使用不正确的密钥和IV大小。但是，由于没有用于密钥或IV扩展的通用方法，这是令人困惑的。因此，您应该确保密钥和IV的二进制表示对于特定算法是正确的

对于AES，您应使用128、192或256位的密钥大小和与块大小相同的128位IV大小。IV应随机生成并与另一方通信，例如，通过在密文中添加IV前缀
