Electronic Code Book (ECB) Mode: Electronic Code Book (ECB) Mode is the simplest form of block cipher encryption where each block of plaintext is encrypted independently. Its main weakness lies in not hiding data patterns well, as identical plaintext blocks produce identical ciphertext blocks. This predictability can lead to security vulnerabilities, making ECBs unsuitable for the encryption of large amounts of data, especially if they contain repetitive information.
