The option @opindex store Store only (make a simple literal data packet). + +@item --add-recipients +@itemx --change-recipients +@opindex add-recipients +@opindex change-recipients +These two commands can be used to change the recipients of an +encrypted file or to add more recipients without fully decrypting the +file. This command works by decrypting just the encrypted session key +and then encrypt the session key to the new recipients given with the +@option{--recipient} options. The output is the entire file with the +recipients added. The advantage over a simple decrypt and encrypt is +that any inner signature is kept intact and that gpg does not need to +actually decrypt the bulk of the data. If +@option{--change-recipients} is used instead of +@option{--add-recipients} all existing recipients are removed from the +output file so than only the newly specified recipients are able to +decrypt the new file.
