Subject: Auto-saving encrypted files
Date: Tue, 25 May 2010 12:42:02 -0400

Package: Emacs
Version: 24.0.50
Severity: wishlist

Currently auto-save is disabled for files that are encrypted by
epa-file.  While auto-saving without encrypting would indeed be
completely wrong, we should make it work right by auto-saving the
file in its encrypted form.
AFAICT, this should be doable by letting the magic file name handler
catch the #.*\.gpg# files as well.

Basically agreed, but a user will be prompted for passphrase each time
symmetric encryption takes place unless she enables passphrase caching.
So we should check the user setting at least.  Currently I don't see any
other issues.
