Encryption / Decryption of String

Cool KeyGenerator for implement in your application.Make your application strong. KeyGenerator generates an unique serial number using the username. Just download it and see the rest. Sorry my bad english.. :P La aplicacion tiene los comentarios en español tambien. :P

This code will encrypt and decrypt files. The files are stored in 2 folders called encrypted and decrypted files on the c drive. These folders are created automatically. Include the following namespaces: System.IO, System.Text, System.Security.Cryptography

This program blocks messenger service spam. I saw that there was no thing for VB.NET so here it is. This code also shows registry adding, keys, shell commands, some basic form functions, system tray icon in VB.NET, getting the application path in VB.NET, short code, tons of comments. A similar program like this might cost you $ 30 on web sites. Get it for free! HOPE YOU GUYS ENJOY IT AND VOTE FOR ME. Visit www.fusai.rules.it for more software.

A file that replaces the old coder.c. Thanks to Brett Taylor. Found at http://www.cprogramming.com/source.html

Checks the HTTP Referer header to ensure people are not posting from other websites. You can include this file if you use templates on your website, or just include it on the pages that receive form data posts. Warning - someone who knows there stuff can get around this by modifying there HOST file. this isn't 100% fool proof, but it may deter most from posting data from other websites.

*UPDATED* Now uses a more recursive and less pattern oriented algorithm. Basically encrypts a text type file using a simple recursive character shift techinque. Pretty basic, but powerful.

*(UPDATED)* ADDED: -Code Re-written -Now updates file size if you no the file has been changed by a program. This program makes a list of all the .ini .sys and .com files on you hard-drive in the c:\windows directory and then calculates there size and keeps them in a log. and then every time the program starts it checks the file sizes against the logged ones to see if they differ, if they do then it tells you. I made this because virusses can sometimes alter files and hide inside them so this basicly keeps a eye on them..

This is an early version of the new password program I am working on, it saves Passwords to disk with very low level encryption and it allows you to call it with-In dos prompt with arguments. Please tell me what you think.

Have you ever fogot a password, but it is still inside your program, only that it is hidden with astricks? This source will show you how to remove those astricks and show whats really there. (see screenshot)

This program is my attempt at encryption. It's fairly secure, I think. It's definitely not a professional job, but it'll do. I devised a funky key representation/generation scheme. Check it out! Read the documentation for much more detail on how to operate it. (Tomb.txt)

This is a password script. Every charachter the user input it displays a star. the password is kcTHEgreat. Catches Control c (Taught to me by a friend :)) so the only way out is to enter the correct password. If you like and think it's secure put it in your autoexec.bat

Yet another password program!! This one takes into account the backspace key, a feature which i didn't find in the other password programs on this site.

Example of how to stream data behind a "facade" file. Stream 1M behind a 1K text file, and explorer/DIR still shows the file to be 1K. According to "Hacking Exposed 2ED" there is only one application that can find these streams.

UPDATED: UI and DLL Free REAL RSA encryption 2048 bits security library. WARNING NOTE: Use this RSA library wisely, I, Hariyanto Lim, the author, will NOT be liable for any damage of any kind caused by this FREE library. This is library is subject to export law of each country, consult your local law adviser (lawyer) before using this library for commercial purpose.

It can load a text file or take typed text and encrypt it using a very simple algorithm. More MFC stuff for school. Hope you like it

This is a professional level app. I wrote it as shareware, but for fellow coders.. well it's all yours. It finds all shares on a domain. then the creeper will search these shares for files that the user defines in the GUI. once found, the app will dl them to your local system. - You can also use it as a security tool to determine how many unsecured shares are on your domain.

Enable or disable the start menu in one line of code.

This is not really meant as a repost of the one Jared Bruni did (there are some similarties, I admit...only in two cases); this is more of a demonstration of a more efficient way to perform the same task (i.e. no dynamic memory required and writting directly to the file). And, just to keep things a little interesting, this one can delete stuff from a list containing filenames. Vote/Comment/whatever, just keep the "you stole someone else's idea" stuff/flames (which I didn't) to a minimum, k? (update: fixed a slight logic bug and added a little extra error checking in the getline function) update 5-12-02: It's fixed now, according to the software I used to test it (R-undelete). Give it a whirl :)

This code allows the user to imput a password (within a C++ program) without any text being displayed on-screen (not even *'s)
