plaintextThis is where the byte flip attack starts to take effect. If we changeCiphertext-N-1(Ciphertext-N-1) a byte, and then different from the next decrypted block or, we can get a different plaintext!You got it?Don't worry. Here is a detailed example. At the same time, the following figure also shows the attack: 0x02 example (CBC Blocks of 16 bytes) For example, we have such a plaintext sequence: A: 2: {s: 4: "name"; s: 6: "sdsdsd"; s: 8: "greeting"; s: 20: "echo 'Hello sdsdsd!

Bash variables are non-typed------------------------Unlike other programming languages, Bash does not differentiate between variables"type"In essence, bash variables are strings. But depending on the context, bash also allows comparison operations and arithmetic operations. The key factor in determining these is whether the values in the variables are only numbers.
