Simplified DES (SDES) Algorithm - Online Code

Description

This is a Java code for Encryption, Decryption and Key generation in Simplified DES (SDES) algorithm used in Cryptography and Network Security. Sample output: >SKT_SDES 0000011111 01000111 Key K1: 01101011 Key K2: 10101010 Encrypted Message: 01101001 Decrypted Message: 01000111

Source Code

class SDES

{

  public int K1, K2;



  public static final int P10[] = { 3, 5, 2, 7, 4, 10, 1, 9, 8, 6};

  public static final int P10max = 10;



  public static final int P8[] = { 6, 3, 7, 4, 8, 5, 10, 9};
