For Procedure of the experiment refer Theory and Manual. +The steps are the following: + +Step 1: Generate Plaintext m, keyA and keyB by clicking on rexpective buttons PART I of the simulation page. + +Step 2: Enter generated Plaintext m from PART I to PART II in "Your text to be encrypted/decrypted:" block. + +Step 3: Enter generated keyA from PART I to PART II "Key to be used:" block and click on DES encrpt button to output ciphertext c1.This is First Encryption. + +Step 4: Enter generated ciphertext c1 from PART II "Output:" Block to PART II in "Your text to be encrypted/decrypted:" block. + +Step 5: Enter generated keyB from PART I to PART II in "Key to be used:" block and click on DES decrypt button to output ciphertect c2.This is Second Encryption. + +Step 6: Enter generated ciphertext c2 from PART II "Output:" block to PART II in "Your text to be encrypted/decrypted:" block. + +Step 7: Enter generated keyA from PART I to PART II "Key to be used:" block and click on DES encrpt button to output ciphertext c3.This is Third Encryption. As Encryption is done thrice.This Scheme is called triple DES. + +Step 7: Enter generated ciphertext c3 from PART II "Output:" Block to PART III "Enter your answer here:" block inorder to verify your Triple DES.
