obfuscation

Hi there,

I'm looking for an easy and reversible method of obfuscating integer IDs. Ideally, I'd want the resulting obfuscation to be at most eight characters in length and non-sequential, meaning that the obfuscation of "1" should look nothing like the obfuscation for "2" and so on.

This isn't meant to be secure by any means, so this isn't a huge concern. Additionally, the integers I'll be obfuscating aren't large - between one and 10,000 - but I don't want any collisions, either.

Does anybody have any ideas for something that would fit this criteria?

Thanks!
Chris

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
