GnuPG it is pretty hard everywhere. Your recent signatures are reported
as "bad" (at least by Notmuch and Mutt). The signed data (message)
doesn't match with the signature.


[...]

The copy I receive from the list does not verify correctly here, either.
It seems somewhere along the path the e-mails content is actually mangled.
-- some additional newlines are introduced compared to my local copy from
the "Sent" folder which verifies correctly.

Attached are `sent.txt` (and `sent.eml`) and `received.txt` -- the very same
e-mail as seen in my Sent folder and Inbox respectively... Interestingly, if
I split out the signatures and message contents, I get bad signature for
both variatns despite the fact that the e-mail client can somehow verify the
sent e-mail...

Consider 7-Zip from Debian package p7zip-full and available for Windows
syswtems: https://www.7-zip.org/

Encrypt on Linux:
$ 7z a -ptestwort -mhe=on secret.7z secret.txt

Decrypt on Windows: Double-Click or use commandline:
% 7z x -o. secret.7z

Alternatively, you could also use aescrypt
(https://www.aescrypt.com/). It is not in Debian but supports a variety of
operating systems including Linux and Windows. GPG should also run on
Windows, but is a little harder to use IMHO.

Hi,

What would be a reasonably secure and simple way to encrypt files on Linux
and then send them to a  non-technical Windows user so she would be able
decrypt and read them?

Any ideas? Thanks
