Encrypt File in VB net

This is a sample application that will encrypt and decrypt files in VB.NET using Rijndael Managed. I started this project because I had several files on my computer that I didn’t want accessible to anyone but me. Sure I could have downloaded a free encryption program off the net, but what fun would that be? So being the hobbyist that I am, I decided to create my own.
Here are some brief descriptions of the cryptographic concepts relevant to this application. I am going to keep things as simple and basic as possible. If you want further details there is a ton of information on the web. Also check out “.NET Encryption Simplified” by: wumpus1 right here at Code Project. These descriptions are based on how the concepts are used in this application.
