WebA key is basically a binary number from 0 to n. The length of the key is 2 n. For example if you choose a 128 bit key, then you can say that your key will be any number between 0 to 2 128. In other words, your key length can be anything between 128 0s to 128 1s. Remember that higher the length of the key, the better your message is protected. WebNext Page. The Data Encryption Standard (DES) is a symmetric-key block cipher published by the National Institute of Standards and Technology (NIST). DES is an implementation of a Feistel Cipher.
