* This is a major rewrite of my old public domain DES code written

* the actual encrypt/decrypt routines are taken from from Richard
* Outerbridge's DES code as printed in Schneier's "Applied Cryptography."
*
* This code is in the public domain. I would appreciate bug reports and

////////////////////////////////////////////////////////
//
// Project: Implementation of IDEA (International
// Data Encryption Algorithm)
//
// ECE Term Project
// Winter
// Author: Irwin Yoon
//
// Overview: This code does the following:
// - print out all encryption and
// decryption subkeys which are used
// in the encryption and decryption
// process
// - encrypts plaintext message
// - decrypts ciphertext message
// - shows detailed, round by round results
// (8 total)
// Program contains a user driven menu where the user can select
// initial -bit key and also select messages to decrypt
// and encrypt.
//
// Compiling: This has been verified to work on SunOS
// with g++ compiler (flop.engr.orst.edu).
// To Compile: g++ Idea.cpp -o Idea.exe
//
// Note: This code is a little sloppy. Coding could
// be made more efficient.
//
// Usage: Run executable with no arguments: Idea.exe
// Then select appropriate menu options
//
