    It is grate to have a posibility of encrypting and signing messages @ Android. Anyway it is not easy to sign or encrypt a file. When choosing the file from the selection dialogue it appears not to be selected when the control gets back to the app. Fortuna

    The vendor-neutral API is a fantastic benefit to all of humanity!
