Encrypting a string

[Bob Hollness]

OK, this has me pulling my hair out. All I want to do is encrypt/decrypt
strings. They may be up to 400 characters in length though.

So, I assume System.Security.Cryptography is the one to use.

All the examples I have found are driving me nuts. They are either way too
long for something that I guess should be fairly straightforward, or I do
not especially trust them as they look pretty bad. The sample from MS only
applies to streams which I am not using.

Does anyone have any help? Sample code, as always, is most appreciated.

Thanks, i'll read through this. It applies to C# though. Do you have a VB
ready version?

Why have MS made this so difficult? If I want to encrypt a string it seems
very long-winded, whereas, if I want to encrypt an entire file there are
plenty of examples from them.
The only example they provide for encrypting a string uses the
RijndaelManaged class and is used to encrypt the key and IV. Either I have
missed something or it is not something easy.

AAARGRGGHHH, Help!!!!!
