YouTube-like GUID

Question

Is it possible to generate short GUID like in YouTube (N7Et6c9nL9w)?

How can it be done? I want to use it in web app.

Answer 1

9 chars is not a GUID. Given that, you could use the hexadecimal representation of an int, which gives you a 8 char string.

You can use an id you might already have. Also you can use .GetHashCode against different simple types and there you have a different int. You can also xor different fields. And if you are into it, you might even use a Random number - hey, you have well above 2.000.000.000+ possible values if you stick to the positives ;)
