Simple password based file decryption/encryption compatible with command line program?

Question

What works currently: With emacs25 (as comes with ubuntu 18) I use ccrypt on the command line to selectively en/decrypt a few specific text files. There is a package elpa-ps-ccrypt which, on encountering such a file, asks for the password, decrypts and lets me edit the file. On save, it encrypts it.

What's wrong: The package elpa-ps-ccrypt does not work with emacs28 (ubuntu snapshot package) for quite some time. It can decrypt, but when saving I get a lengthy error-message.

What I would like: I guess I should switch. But what is a decent successor?

Musings: erc-crypt and kaesar mention "openssl", which makes me cringe. But maybe that is what is the right thing to do? Or is it easier to define a save and a load action to transform files on writing and reading? How would that be done with asking the password?

Answer 1

On ccrypt.sourceforge.net I found version 1.11 of ccrypt which comes with a ps-ccrypt.el that works with emacs 28.0.50. It is easy enough to activate that file:

1. Put the file into .../whateverdir.
2. If whateverdir is not listed in variable load-path, add it in one of your emacs startup files like (add-to-list 'load-path ".../whateverdir")
3. In that same startup file add (require 'ps-ccrypt).

Now it works again. (Disclaimer: I shyed away from sourceforge at the time of writing the questing because, well, its sourceforge :-( and the page takes ages to load).
