When working with signal processing, I use zeros to pad signals: # Original signal signal = np.array([1, 2, 3, 4, 5]) # Pad with zeros (zero padding is common in signal processing) padded_signal = np.zeros(10) padded_signal[:len(signal)] = signal ...
OK这俩一致了,那么OpenSSL是怎么回事?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 zer...
