WebMay 4, 2016 · The ciphertext clearly does not need to be secret. And the IV serves as the ciphertext input for the first block. If the first block were not secure with a known IV, the second block would not be secure with known ciphertext, and ciphertext is known. So if the second block is secure, the IV need not be kept secret. – David Schwartz WebMay 11, 2024 · Ciphertext is a series of randomized numbers and letters that humans cannot make sense of.
