@ -19180,6 +19180,16 @@ Here is a suggestion for Org Crypt settings in Emacs init file:
;; # -*- buffer-auto-save-file-name: nil; -*-
#+end_src
It's possible to use different keys for different headings by
specifying the respective key as property =CRYPTKEY=, e.g.:
#+begin_src emacs-lisp
,* Totally secret :crypt:
:PROPERTIES:
:CRYPTKEY: 0x0123456789012345678901234567890123456789
:END:
#+end_src
Excluding the =crypt= tag from inheritance prevents already encrypted
text from being encrypted again.
