A lot of new hacking methods are coming day by day. So it’s the programmers duty to make their user’s password secure. Here is a simple Password Strength Checker created using jQuery. The code contain a function got from WordPress (I modified it) which is the core component of the checker. This checker will check the following on the password :

1. Have minimum value of 4 characters.
2. Whether the username matches with password
3. Whether the password contain small a-z characters and capital A-Z characters.
4. Whether the password has numeric characters and special characters.

If all of the above criteria is matched, the checker will give a Strong Password message.

I made a URL shortening service a year back using PHP & jQuery. It was pretty simple. You should know the concept of URL Shortening. The concept is simple. When a user sends a request to short a URL, PHP will check if the URL is valid. If it’s valid then PHP will make a string of 5 or 6 characters.
