You will perhaps know that in ECB (Electronic Code Book) mode in AES, you will always get the same ciphertext for the same key. As this is a block cipher, the padding will change the end characters, but as long as we have 16 bytes then the first block will be the same. But what about the modes that use an IV? Well, let’s look at a…
