WebElectronic Code Book (ECB) Mode This mode is a most straightforward way of processing a series of sequentially listed message blocks. Operation The user takes the first block of plaintext and encrypts it with the key to produce the first block of ciphertext. WebWhat is the ECB Penguin? The most common encryption algorithm, AES, is a block cipher with 128-bit blocks. A block cipher always encrypts the same contents the same way, given the same key. Naively, that doesn't seem like a problem because that output is still encrypted, and hence "secure", but it reveals information. We can see that two ...

WebElectronic Code Book (ECB) is the simplest and weakest form of DES. It uses no initialization vector or chaining. Identical plaintexts with identical keys encrypt to identical ciphertexts. Two plaintexts with partial identical portions (such as the header of a letter) encrypted with the same key will have partial identical ciphertext portions.
