--try-secret-key name
              For hidden recipients GPG needs to know  the  keys  to  use  for
              trial  decryption.   The  key  set  with --default-key is always
              tried first, but this is  often  not  sufficient.   This  option
              allows  to  set  more  keys  to  be  used  for trial decryption.
              Although any valid user-id specification may be used for name it
              makes sense to use at least the long keyid to avoid ambiguities.
              Note that gpg-agent might pop up a pinentry for a lot keys to do
              the  trial  decryption.   If  you want to stop all further trial
              decryption you may use close-window button instead of the cancel
              button.
