Notes:

This is a modifed WebForm demo I originally created for a WinForm App. Download the project.

I got the idea from a TripleDES wrapper I found and proceded to make other wrappers. See the code by selecting TripleDES Wrapper and click Show File.

Select the algorithem to use, type the text you want encoded. Then try and decode it.

Data Proection API

This algorithm uses the built in API in the Windows server. For some reason, I never got the user account to weork. Try the machine account.

DES and TripleDES

The Data Encryption Standard is a common algorithm. TripleDES is basically the DES ran three times.

RC2

RC2 is actually a cipher and probably not thre most effective algorithm.

Rijndael/AES

The Advanced Encryption Standard algorithm is onr of the best.
