    example: encrypt file
    
    * Example to encrypt a file to a single key.
    * Takes key ID and/or fpr as a CLI parameter.
    * Takes path and filename as a CLI parameter.
    * Encrypts to specified key only, no signing and writes the output in
      both ASCII armoured and GPG binary formats with output filenames
      based on input filename.
