[William Greger]

1. GUI mode
    - select a file, right click
    - resulting menu includes   Encrypt..
    - select   Encrypt.. ;fill in resulting menu and file gets encrypted
   CLI mode
    - what is the equivalent command to  encrypt  a file?

2. crypt  command
    - Ubuntu basic installation does not include the  crypt  command
    - can/does Ubuntu support the  crypt  command?
      * if yes, how do I get, install  crypt?
