+\r
+My bank frequently sends me transactions as an inline-armored gpg\r
+encrypted text. So I added the below 2 lines in my .emacs and added this\r
+function to the list of notmuch-show-hook functions:\r
+\r
+(defun spaetz/decrypt ()\r
+  (epa-decrypt-armor-in-region (point-min) (point-max)))\r
+\r
+Despite warning in the docs that this function should not be called from\r
+elisp programs directly, it works just fine for me. The only annoyance\r
+is that the function asks "Should I replace the current text (y/n)" in\r
+the status bar whenever it detects gpg text.\r
+It works for me and is a nice proof-of-concept which happens to solve my bank\r
+account itch, but definitely needs improvement:\r
+\r
+- We just feed it the whole notmuch-show buffer, it would be nicer to\r
+hand it the just the region of the message body/mime part. I wonder, if\r
+things like this should not better be done with dme's message-washing\r
+hooks rather than a notmuch-show hook?  \r
+\r
+- The annoying "should I replace the current text" question should not\r
+appear, ie we need to use some more low-level functionality and\r
+implement mime part "cleaning".\r
+\r
+- This will not handle encrypted text as an mime attachment, I guess.\r
+\r
+No clue, just tossing this out for now.\r
+\r
+Sebastian\r
