OpenSSL也是默认pad/unpad的,可以通过-nopad参数来取消。但是无论加还是不加都和上面两个产生的结果不一致。另外还有-nosalt,但是似乎对AES-128-CBC算法并没有区别。 我在网上搜了半天也没什么头绪,不过发现运行时OpenSSL有个提示:hex string is too short, padding with zero bytes to length。会不会有关系?我...

4 and 5 were padded with zeros in this way. 11.2.4 Using the TextVectorization layer Every step I’ve introduced so far would be very easy to implement in pure Python. Maybe you could write something like this: python中self相当于java中的this,表示当前类的对象,可以调用当前类中的方法和属性。
