请教一个关于AES的ECB解密的问题
我有一个bat批处理，它的功能是下载某网站的视频，视频有加密，该脚本是调用OpenSSL命令进行解密。解密命令如下：
openssl aes-128-ecb -d -in "被加密的视频文件路径" -out "解密后的视频文件输出路径" -K key字符串
上面这行命令的意思是：调用OpenSSL，-d 解密；-in 输入文件的路径；-out 输出文件的路径； -K 密钥
通过BAT批处理调用这行命令能解密成功顺利播放，但是当我使用python代码尝试实现这个效果的时候，发现视频解密后无法播放，也就是没有解密成功，python实现这个功能的代码如下：
crypt = AES.new(key.encode("utf-8"), AES.MODE_ECB)
plain_text = crypt.decrypt(data) #data是视频的二进制流
return plain_text.rstrip(b'\0')但是我发现您的代码是这样写的：
def decrypt(data, key):
cipher = Cipher(algorithms.AES(key), modes.ECB(), backend=default_backend())
decryptor = cipher.decryptor()
return decryptor.update(data) + decryptor.finalize()其实我不太理解您的这个Cipher(algorithms.AES(key), modes.ECB(), backend=default_backend())写法，您看看我需要如何改进代码？
