remove from each line in @var{recpstring}. The keys are then passed
verbatim to the backend engine.
For the OpenPGP backend two special keywords are supported to modify
the operation: If the keyword "--hidden" is given as a recipient, it
is skipped but will trun all following key specifications to be hidden
recipients. If the keyword "--" is given as a recipient, it will be
skipped but no keywords will be detected in all following key
specifications.
For the OpenPGP backend several special keywords are supported to
modify the operation. These keywords are given instead of a key
specification. The currently supported keywords are:
@table @code
@item --hidden
@itemx --no-hidden
These keywords toggle between normal and hidden recipients for all
following key specifications. When a hidden recipient is requested
the gpg option @option{-R} (or @option{-F} in file mode) is used
instead of @option{-r} (@option{-f} in file mode).
@item --file
@itemx --no-file
These keywords toggle between regular and file mode for all following
key specification. In file mode the option @option{-f} or @option{-F}
is passed to gpg. At least GnuPG version 2.1.14 is required to handle
these options. The @code{GPGME_ENCRYPT_WANT_ADDRESS} flag is ignored
in file mode.
@item --
This keyword disables all keyword detection up to the end of the
string. All keywords are treated as verbatim arguments.
