AES Encryption: What's the difference between the IV and Key? Why do we need an IV?
AES is deterministic. Encrypting the same file, with the same key and IV will only reveal that you encrypted the same file twice (the ciphertext. Different Modes of AES Encryption � ECB(Electronic Code Book) is the simplest encryption mode and does not require IV for encryption. � CBC(Cipher Block Chaining). (The core AES operation only works on byte blocks. A mode is a way to extend this to longer messages.) For example, with CBC, the encryption.

If an attacker knows the IV or the previous block of ciphertext before he specifies the next plaintext, he can check his guess about plaintext of some block that was encrypted with the same key before. It is usually implemented as a persistent counter. Cookie Policy. To set a new IV on a keyed cipher use Resynchronize.
