This is not directly supported by GPGME.  You need to write an edit
interactor to control the gpg --edit-key command.  GPA has code which
shows how to do it.

That is useless.  You are changing a returned value for display.  It
does not make any sense to change it.



Die Gedanken sind frei.  Ausnahmen regelt ein Bundesgesetz.
