I know that this is basic but I'm proud of it, considering that I'm still learning c++

Code: Select all

//----Simple Encryption / Decryption using XOR
// Written by Talbas March 8 2006


#include <iostream>

int main()
// Encryption Routine - replace the key and string with own data
{
char string[11]="talbas20011";
char key[11]="ABCDEFGHIJK";
for (int x=0; x<11; x++)
{
  string[x]=string[x]^key[x];
  std::cout << string[x];
}
// Decryption Routine - I placed this here to verify encryption
std:: cout << "\n";
for (int x=0; x<11; x++)
{
  string[x]=key[x]^string[x];
  std::cout << string[x];
}

return 0;

}


Good for you!
I know it doesn't seem that big of a deal, but mastering small projects like that will prepare you for working on bigger and better things.
Code on!

You might also want to consider expanding the key so that you can encode any length string.

Nice. Simple, but a good learning project.
I didn't even know there was an XOR operation in C++. Cool use of it.

Heh, XOR is nice... as far as you key bigger then the plaintext
but still nice

There is a way to use short key for big plaintext - just repeat it over and over ;).

Now I'm definitely a C++ noob, but I think you can make your XOR program a little more flexible in string sizes by using the string library rather than allocating a 15-char array (one char of which must be taken up by the \0 terminator). Just a thought...

Good starting point. Just don't panic when NSA knocks on your door and puts you in a room (and they throw away the room)...

I'm kidding. But seriously they take encryption seriously, because they get pissed off when they can't crack your email messages...

You might be interested in doing some research on PGP...
