Hello,

I need to encrypt and decrypt a string in .NET Framwork 2.0.

What is the easiest way to do it?

I know that there are many different ways to use encryption in .NET,
some more complex than others. All I need is to hide from an end-user
some clear-text settings -- nothing super secretive.

The reliability of the encryption routine and the easy of development
are the primary goals.

Thank you for your advice.

As you say it's nothing super secretive, so I'm assuming that you just
need to encrypt something so the average user doesn't mess about with it.

If that is the case, a simple base64 encoding and decoding method would
do the job.

Regards,

Richard

Eugenet,

I see that you have these goals.

What do you think other people want?

However here the starting links of the encrypting methods in Net

If you need to hash something, I'd use System.Security.Cryptography.MD5 or
another class from the Cryptography. Heck, if I needed to do anything
cryptographically, I'd use the System.Security.Cryptography namespace :)

Thank you for your posts. For my purposes, base64 encoding is the way
to go.

if you want to do something reallyreallysimple, use an XOR algorithm.

You only need one method, it will XOR each character against a known value
(from 0 to 255 for ASCII) and spit out an xor-ed string that is the same
length as the original. To Decrypt it, send the xor-ed string back into the
same method. You can do all this in about 5 lines of code.
