Recipe 7.23 Maintaining Encrypted Files with Emacs

7.23.1 Problem

You want to edit encrypted files in
place with

GNU Emacs, without decrypting them to disk.

7.23.2 Solution

Use the Emacs package
crypt++.el:

~/.emacs:
(if (load "crypt++" t)
(progn
(setq crypt-encryption-type 'gpg)
(setq crypt-confirm-password t)
(crypt-rebuild-tables)))

7.23.3 Discussion

crypt++ provides a transparent
editing mode for encrypted files. Once the
package is installed and loaded, simply edit any GnuPG-encrypted
file. You'll be prompted for the passphrase within
Emacs, and the file will be decrypted and inserted into an Emacs
buffer. When you save the file, it will be re-encrypted
automatically.
