Just discovered a bug in my previously posted function. It doesn't work
too well if you have lower level subtrees tagged for encryption.
Here is the fixed version:

(defun aleblanc-org-toggle-encryption (rcpts passphrase)
  (interactive (list (split-string (read-string "Recipients (default is none): ") "[ \t,]+")
		     (pgg-read-passphrase "GnuPG passphrase: ")))
  (show-all)
  (org-map-entries '(let (start end teststring)
		      (org-outline-level)
		      (next-line)
		      (org-beginning-of-line)
		      (setq start (point))
		      (setq teststring (buffer-substring start (+ start 27)))
		      (outline-get-next-sibling)
		      (if (not (equal (point) (point-max)))
			  (previous-line))
		      (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"))
