WebJun 21, 2024 · Encryption is a process of encoding messages such that it can only be read and understood by the intended parties. The process of extracting the original message from an encrypted one is called Decryption. Encryption usually scrambles the original message using a key, called encryption key, that the involved parties agree on.

WebAug 14, 2024 · ECB (Electronic Codebook) is the most basic mode of AES. It can be explained in two steps: Step 1: the plaintext is divided in blocks of 16 bytes P = [P1, P2, ..., PN] P = [P 1,P 2,...,P N] Step 2: each plaintext block is encrypted to produce the ciphertext blocks : C1 = E_k (P1), \quad C2 = E_k (P2), ...
