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.
