The new function is `org-crypt-use-before-save-magic'. When called, it will add a before-save hook that encrypts all tagged entries. Example usage: (require 'org-crypt) (org-crypt-use-before-save-magic) The before-save hook stuff is still experimental. Please let me know what you think. --=-=-= Content-Type: application/emacs-lisp Content-Disposition: attachment; filename=org-crypt.el ;;; org-crypt.el --- Public key encryption for org-mode entries ;; Copyright (C) 2009 Peter Jones ;; Copyright (C) 2007 John Wiegley ;; Emacs Lisp Archive Entry ;; Filename: org-crypt.el ;; Version: 0.4 ;; Keywords: org-mode ;; Author: John Wiegley ;; Maintainer: Peter Jones ;; Description: Adds public key encryption to org-mode buffers ;; URL: http://www.newartisans.com/software/emacs.html ;; Compatibility: Emacs22 ;; This file is not part of GNU Emacs. ;; This is free software; you can redistribute it and/or modify it under ;; the terms of the GNU General Public License as published by the Free ;; Software Foundation; either version 2, or (at your option) any later ;; version. ;; ;; This is distributed in the hope that it will be useful, but WITHOUT ;; ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or ;; FITNESS FOR A PARTICULAR PURPOSE.

It depends ;; on the epg library. Here's how you would use it: ;; ;; 1. To mark an entry for encryption, tag the heading with "crypt". ;; You can change the tag to any complex tag matching string by ;; setting the `org-crypt-tag-matcher' variable. ;; ;; 2. Set the encryption key to use in the `org-crypt-key' variable, ;; or use `M-x org-set-property' to set the property CRYPTKEY to ;; any address in your public keyring. The text of the entry (but ;; not its properties or headline) will be encrypted for this user. ;; For them to read it, the corresponding secret key must be ;; located in the secret key ring of the account where you try to ;; decrypt it. This makes it possible to leave secure notes that ;; only the intended recipient can read in a shared-org-mode-files ;; scenario. ;; ;; 3. To later decrypt an entry, use `org-decrypt-entries' or ;; `org-decrypt-entry'. It might be useful to bind this to a key, ;; like C-c C-/. I hope that in the future, C-c C-r can be might ;; overloaded to also decrypt an entry if it's encrypted, since ;; that fits nicely with the meaning of "reveal". ;; ;; 4. To automatically encrypt all necessary entries when saving a ;; file, call `org-crypt-use-before-save-magic' after loading ;; org-crypt.el. ;; ;; TODO: ;; - Allow symmetric encryption as well ;;; Thanks: ;; - Carsten Dominik ;; - Vitaly Ostanin (require 'epg) (defgroup org-crypt nil "Org Crypt" :tag "Org Crypt" :group 'org) (defcustom org-crypt-tag-matcher "crypt" "The tag matcher used to find headings whose contents should be encrypted.
