TRAMP and encrypted archive access

TRAMP and encrypted archive access

[Ihor Radchenko]

Hi,

I am studying options to extend org-crypt encryption to attachment files
in addition to text inside Org buffers.

I do know that Emacs allows transparent access to encrypted files and I
also know that TRAMP is able to open archive files (like .tar)
transparently as directories.

I thought that combining these two features should just work™, but
apparently it is not the case. If I create a foo.tar file, I can open it
with TRAMP. But the encrypted version of foo.tar.gpg file does not work
- it opens in tar-mode instead.

Am I missing something? Or may my idea be silly?

The combination as in foo.tar.gpg/ is not supported yet in
tramp-archive. tramp-archive supports compressed files, not encrypted
ones. Yet.

Might be possible, but I need to think about.

For your own purposes in org-crypt, you must ensure that foo.tar.gpg,
after decryption, is opened at foo.tar/ - the trailing slash matters.
