Hello Again! Here is my second submission to PSC, and its a complete Software Protection System, to protect the software you've worked on so hard to develop, from illegal copying or un-authorised use. In the core of the system is the SoftwareLock Class, which needs to be compiled by a VB.NET compiler as a DLL, that done you can use it in any .NET languages to provide protection for your software. I've also included a sample project (SoftwareLockDemo) which demonstrates how to implement the various properties and methods SoftwareLock exposes. The third project included in this package is the Softwarelock Key-genarator application, which you can use to generate Serial Keys for your customers. How does SoftwareLock work??? ... Well, you basically supply a codename (AppName property), and a password for your application, SoftwareLock combines these strings along with your customer's hard disk serial number and using complicated encryption algorithms from System.Security.Cryptography namespace, it generates a customer reference for the customer, you have to display this reference to your customer, the customer then has to contact you and quote the Reference he/she's been given. Using the reference provided, AppName, Password, and a Hash Algorithm you specified the SoftwareLok Key-generator generates a unique Serial Key, which you have to give to your customer to unlock his/her software. Thus, by supplying your custom appname and password, you protect your software from other SoftwareLock users. By using your customer's unique Hard disk serial, you protect your software from un-authorised copying and make it unique to the machine it was initially registered on! Please note that SoftwareLock uses a logical disk drive's serial number supplied by the operating system when the disk was formatted, NOT the manufacturer's serial number! So if your customer has to format his drive for some reason, you will have to generate a new serial key based on the new hdd serial number, or your program won't run. while developing SoftwareLock I first tried to let it use the Manufacturer's HDD serial no, using System.Management, and WMI Queries. But later i realized that the the method i was using only worked on WinXP and Win2000 operating systems. I haven't yet figured out an API approach to the problem. If you know anything, please share it with me!!! Thank You.

Encrypts and Decrypts a file. This is not an "uncrackable" type of encryption but once you can understand the basics of this type of file encryption you CAN make better ones than me. This is just a quick example of basic encryption. Highly commented to help beginners. There aren't many good examples on PSC, maybe this one is :), to me, comments are more useful than votes. simple Encrypt / Decrypt.

This program takes a password and replaces it with * while typing it. It features deleting and password length limits.

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

IAO login is an authorization suit, which enhances the security of your private pages. It uses best security algorithms to protect your data and pages from cracker. It uses GIMPY Captcha to fight against Spam Bots and automated submitting. Users can login even in cookie disabled browsers. Feel free to manage your users at administration panel and send newsletters to your users. Add more administrators and describe their role. It doesn't use ANY DLL and hence easy to install and use own various web servers.

Purpose:- Save Time and Labour while clearing CMOS setup password.. Now you donn't need to open your computer and make jumper setting for clearing CMOS setup password. Here is the utility for that purpose. 100% tested on IBM or IBM compatible PC.

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.

This is a pretty nice and clean MD5 sum for strings. Just Copy and Paste it in. Sorry if it gets bucherd by PSC

FileMinator is a tool to securely remove files eliminating the possibility of recovery. You may need it when you leave important information or software in someone else computer, or when you are selling yours.

This is the tweaking tool, task manager dan system information. There are over 30 triks to manipulate Windows by registry. Please give me your vote and may be your sugestion to repair and make it better

A simple drop-in class to create random passwords. Outputs the password as well as a SHA1, MD5 and salted hashed password if request. Simply drop this class into a folder and reference the Usage section in the PHP file for information on how to use. I also included a UUID creator so making advanced salt values is easy. Enjoy and vote!

This code can check if the user that is logged on to windows is an administrator.

Ok, this project work by copying an entire process directly into anothers memory space. This will not work on all running processes because the ImageBase required by the injector executable maybe already Allocated by the process, therefore causing the VirtualAllocEx to fail. If you were to make this work on all process you would first have to rebase the injector in memory, then inject it. I hope this has answered your question to why this fails on most processes. The default imagebase for an executable most of the time is 0x400000 which is available in Explorer.exe, so i chose to use that process as my example.

This project allows you to replace an existing DACL(Discretionary Access Control List) within a process. When you do so, you have the power to restrict certain capabilities like terminating, getting a handle to the process, reading memory, writing memory, etc. This example stops all access to the process from any other process of lower privileges. Always remember that this can be subverted by a NT AUTHORITY\System owned process. This just stops the common user from closing your process. Thanks everyone for your support. If you like this then drop a line, and don't forget to VOTE and show me what you think of my work. Sincerely, ANUBIS

This software is an update to the last version which was very limited in it's functionality. Whenever you tried to inject a process into another process that was using the required ImageBase, VirtualAllocEx would fail and cause the injection to fail as well. Well i fixed this problem by rebasing every address within the relocation section of the executable. And by doing this I came up with a way to inject an executable into *ANY* process that you have privileges to inject into. Now a days linkers by default leave out the .reloc section because it is not needed for an .exe. So for this to work you need to use the switch for your linker that will turn on the relocation section output. Thanks for your patience, and most of all thanks for your vote. .::ANUBIS::.

This code will hook any api of your chose and allow you to redirect it to another qualified function. This code can be used in conjunction with my other posts dealing with process injection to hook api's in other running processes. Thanks for voting!!
