Sure. My config is on
https://github.com/novoid/dot-emacs/blob/master/config.org and I've
set it with:

(setq org-crypt-key "ABC12345")  ;; I may have to mask this online as well ;-)

: grep -i CRYPTKEY *
... is empty when applied to my Org-mode files.

The only thing to fix my situation was to re-import a non-expired
version of my default OpenPGP sec key.
