how to use org-crypt with different key per file or node?

how to use org-crypt with different key per file or node?

[Gregor Zattler]

Dear org-mode users and developers,

I use org-crypt for different org files.  Till now I follow the
documentation and specify the one and only key to use via
(setq org-crypt-key "0xdeadbeef") for all org files and their
headings.

Is it possible to specify different keys for different files or
even better for different headings?


Ciao; Gregor

AFAICT there is property CRYPTKEY for that.  Possibly this has been
forgotten in the info documentation for org.

Example:

* totally secret :crypt:
:PROPERTIES:
:CRYPTKEY: 0x0123456789012345678901234567890123456789
:END:


HTH

 Excluding the =crypt= tag from inheritance prevents already encrypted
 text from being encrypted again.

Thank you.

I used =CRYPTKEY= instead of CRYPTKEY, as it is meant to be written in
an Org document.

There was a missing comma in front of the headline.

I applied your patch with the changes above.

Indentation is not enough!?  Is there a document describing how
to contribute to org-manual.org?

PS: I guess this should have been "#+begin_src org" instead.

Actually, we settled on "#+begin_example" instead, because of
fontification issues.

Fixed. Thank you.

[stardiviner]

Can let this property CRYPTKEY support interactive select keys from minibuffer?

Manully input is not an good choice obviously.

How to let org-mode property auto prompt for a list of keys after
inserted property key "CRYPTKEY"?
