*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.

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)

***Disabling CTRL-ALT-DELETE on Windows NT, Windows 2000, and Windows XP*** There is an undocumented way to disable the Ctrl Alt Del key sequence on Windows NT/2000/XP using the registry. The key, 'HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon : AutoAdminLogon (REG_SZ)' has only two legal values, according to Microsoft: "0" and "1". 0 disables automatic logon of the account stored, and 1 enables it. The strange thing is that if you set the key to "2"...

This is a simple passowrd program that prints '*'s at the prompt. *UPDATED* Now the code allows you to use the 'backspace' key. Please leave feedback and let me know what you think.

With NTFS partitions, intruders can hide their toolkits behind a 'front file'. Explorer and DIR only show the front file and the size of the front file, leaving no clue as the hidden 'back streamed' files. This code finds them. You can back stream a file like this "copy MyTrojanProgram.exe SomeSystemFile.ini:MyTrojan.exe" SomSystemFile.ini will stay the same size and the backstreamed trojan will be almost undetectable.

This is a programm (written in Assembler) that saves a file on a disk in RAW format, without FAT or anything. This means that data will be saved on your disk but it will be able to read only by your programm.

Its an aunthication Program which you can use it to load at the windows startup by using Autoexec.bat file.
