Encryption works on bytes (in and out). 

However it's easy to convert a string into a byte array (input), encrypt
it and the convert the (encrypted byte array) into a base64 string
(which is a valid UTF8 string).

There are variations but trying to be simpler than that (3 steps) will
only cause you pain.

Sure you used Google ?

The namespace is System.Security.Cryptography. However you won't find a
class that deals with strings in it. The conversion (string/bytes) can
be done using System.Convert class and using the encoding classes in the
System.Text namespace.
