Progress on 0.3:

Code: Select all

v 0.3
- Code fixes. Instead of adding a new line in every function, just add a new line in the command function.
- Improved set system, less code and more efficient.
- You can now start a process directly from a path(C:\ for example);
- Added a new command THROW (pretty useless)
* throw [Exception] - Throws an exception
- Added a new command GAME
* game <game> - plays a game
* if you play fourinarow, you type exit as a row, it will exit.
- Bug with a set argument fixed

Here is something else.

It allows you to encrypt and decrypt messages using a password.

/encrypt [password] [message]
/decrypt [password] [message]

The command method is an example, I'm not sure how you are going to code it exactly into your source, but there is an example of how the if statement will work.

The other methods are used to operate the command.

Code: Select all

       private void command(string message)
        {
            if (message.IndexOf('/') == 0)
            {
                message = message.Substring(1).TrimStart();

                if (message.Contains(" ") && message.Split(' ').Length >= 2)
                {
                    if (message.Split(' ')[0].ToLower() == "encrypt")
                    {
                        onEncrypt(message.Split(' ')[1], message.Split(new char[] { ' ' }, 3)[2]);
                    }
                    else if (message.Split(' ')[0].ToLower() == "decrypt")
                    {
                        // Can just use Split[2] here as encrypted strings do not have any spaces within them
                        onDecrypt(message.Split(' ')[1], message.Split(' ')[2]);
                    }
                }

            }
            command(Console.ReadLine());
        }

        private void onEncrypt(string code, string toEncrypt)
        {
            string Encrypted = Encrypt(toEncrypt, code);
            Console.WriteLine("Encrypted message: ");
            Console.WriteLine(Encrypted);
            Clipboard.SetText(Encrypted);
            Console.WriteLine("This message has been copied to your clipboard.");
        }

        private void onDecrypt(string code, string toDecrypt)
        {
            string Decrypted = Decrypt(toDecrypt, code);
            Console.WriteLine("Decrypted message: ");
            Console.WriteLine(Decrypted);
        }

        // If you change this, byte[] array must be >= 8
        private readonly byte[] _salt = Encoding.ASCII.GetBytes("Conor12345:D");

Dependable references:

using System;
using System.IO;
using System.Security.Cryptography;
using System.Text;
using System.Windows.Forms;


In case you can't figure out why System.Windows.Forms won't appear; a console application does not automatically add a reference to System.Windows.Forms.dll, right-click your project in Solution Explorer and select Add reference, and then find System.Windows.Forms and add it.

Wow! This is something cool! Thank you!
I am going to use it in some way.
But why do you need

Code: Select all

System.Windows.Forms

?

For the one usage of the Clipboard class.

You can put it directly into the code instead, if you'd prefer.

Code: Select all

System.Windows.Forms.Clipboard.SetText(Encrypted);


I am planning to liquidate this project due to lack of interest(And also my interest).
It was nice as long as it took. I thank Conor for all his code.

And the release of 0.3:

CyberCriminal will be liquidated in two weeks unless there will be more interest in this project.

Thank you all.

Incredible program, you have grew so much since you joined here, you used to be a coder that has to learn code from other users', in public, you generated such finery in code this year, your work is outstanding, we are all very proud to have you here Yoppie.
-Lucas

So...this was liquidated? sad.
