The idea is that when the client connects to a server, each of the nodes create a pair of keys, and each send their public keys to the other side. after that each node encrypts the data using the other node's public key and decrypts the data it recieves using its own private key. almost impossible for a sniffer to decrypt the data. Remember that this is a just a sample on how to do this and it does not have many features including events and async data tranfer.

This is the ASP version of a CGI technique used to scare off spammers (or at least to make things harder for them) that use email extractors to collect addresses from web sites. The script generates a random number of fake Email addresses and URLs that call itself in an endless loop. The result: email extractors get clogged with fake addresses. A META tag tells search engine robots not to index the page. To use just rename the file to anything you want (example: test.asp) and put a hidden link to it on your site, like this: [A HREF="wpoison.asp"][/A] (replace [] with <> respectively). Please help spread the word about web poisoning, it might not stop spammers, but will surely slow them down!

Simple way of preventing access to your client side javascripts and even style sheets

Prevent unauthorized viewing of website javascript and style sheet files. Simply rename all your style and javascript files to the .asp extension. Then include the validate_view.asp file at the top of each file. Open the validate_view.asp file and change the top the constants to those required. Then finally call the procedure name "validate_view" with the current files content type as the parameter.

This code will take the users username and password from a form and use them to authenticate them against a Windows NT/2000 domain. Unlike other examples, you do not need to switch on 'Basic' or 'Integrated Windows' permissions for the webite on IIS. You can leave the setting as Anonymous Access.

*(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.
