            If for whatever reason the method
            fails to complete, the method will return some text stating exactly
            what has gone wrong. 
             You need to specify the PublicKey
            to use when encrypting the text. The public key has to be an extracted
            public key, such that you pass it into the control as a string. 
            If you have public and private
            keyrings you can use the  ExtractKeys method of
            Cryptocx to extract a specific public key then pass it back to the control via the
             PublicKey property and then encrypt some text using
            it.
             You need to set the WorkingFolder
            property of the control to a directory that the process that will
            call Cryptocx will have full read/write access.
