Couldn't find the org-mark-subtree function, but the following code
works for me.
It will toggle the encryption of all subtrees in the current buffer that
are tagged with :ENCRYPT:, i.e. if the subtree is encrypted (starting
from the first line after the header, and finishing on the last
non-empty line of the subtree), it will be decrypted, otherwise it will
be encrypted.
You can use either gpg keys or a passphrase to encrypt subtrees. To use
gpg keys, enter the names of the owners of the keys at the prompt,
otherwise just press enter to use a passphrase only.
If the passphrase does not match for any encrypted subtrees they will be
left as is.
Perhaps someone could post this on Worg? (I am lazy).
(defun org-toggle-encryption (rcpts passphrase)
(interactive (list (split-string (read-string "Recipients (default is none): ") "[ \t,]+")
(pgg-read-passphrase "GnuPG passphrase: ")))
(org-map-entries '(let (start end teststring)
(org-show-subtree)
(next-line)
(org-beginning-of-line)
(setq start (point))
(setq teststring (buffer-substring start (+ start 27)))
(condition-case nil
(progn
(outline-forward-same-level 1)
(previous-line))
(error (goto-char (point-max))))
(org-end-of-line)
(setq end (point))
(if (equal teststring "-----BEGIN PGP MESSAGE-----")
(if (pgg-decrypt-region start end passphrase)
(pgg-display-output-buffer start end t)
(message "Can't decrypt region!"))
(if (equal rcpts '(""))
(pgg-encrypt-symmetric-region start end passphrase)
(pgg-encrypt-region start end rcpts nil passphrase))
(pgg-display-output-buffer start end t)))
"+ENCRYPT"))
