WebJan 26, 2013 · DES (Data Encryption Standard) is a block cipher algorithm. It’s one of the most basic symmetric encryption mechanisms, which means that both the encryptor and the decryptor has to know the secret key in order to perform their respective actions. So the basic steps of this tutorial are : Generate a secure, secret key using a KeyGnerator. WebThe Data Encryption Standard (DES) is a symmetric-key block cipher. In the year 1977, DES is published by the National Institute of Standards and Technology (NIST). It is based on the Feistel structure in which the plaintext is separated into two halves. It takes input as 64-bit plaintext and a 56-bit key to produce 64-bit ciphertext. cindy rochelle graham
