EMACS 23.1.1 and crypt++

EMACS 23.1.1 and crypt++

[Felix E. Klee]

Yesterday, I upgraded to EMACS 23.1.1/WinXP, from some version of
EMACS 22. Unfortunately, now crypt++.el does not behave correctly
anymore:

When I open a file with extension ".gpg", as configured, it correctly
asks for a password and presents a buffer with the decrypted contents.
However, when I try to save the file, the it firsts asks whether it
should be stored encrypted, and then for the password. This behavior
is unwanted. I want crypt++.el to always save the file and encrypt it
with the password I specified earlier.

How do I get back the old behavior?

PS: Yes, I already tried XEmacs' "crypt.el": same problem.

Emacs 23 comes with built in support for file encryption through the
incorporation of easyPGP as part of standard emacs. 

At a guess, I would say that it is easyPGP that is doing the encryption
or possibly you are getting unwanted interaction between crypt++ and
easyPGP. 

My suggestion would be to remove crypt++, then see if you can configure
the built-in encryption/decryption support to show the behavior you
want. If that doesn't work, then maybe investigate how to disable the
built-in package and load crypt++. I'm not sure how actively crypt++ is
maintained while the built-in functionality is almost certainly going to
be, so it would make sense to migrate to that provided it will function
in a way that meets your needs and doesn't frustrate too much due to how
it is different.

Thanks, Tim! With the following customization and crypt++.el/crypt.el
disabled, I have the old behavior back:

 '(epa-file-cache-passphrase-for-symmetric-encryption t)

You should also consider:

1) auth-source.el can save the password so you never have to enter it,
even the first time.

2) setting up a private key for GPG may work best for you, since you can
then use it for other purposes and in other programs as well.
