Ich denke, es ist Zeit, sich mit der Verschlüsselung von E-Mails zu beschäftigen. Zu diesem Zweck empfehle ich #GnuPG.
Für Windows-Nutzende gibt es da ein schönes Rundum-Sorglos-Paket, #GPG4Win. Und wer #Thunderbird nutzt, hat GnuPG ohnehin schon parat.
#gnupg 2.5.2 released; see https://lists.gnupg.org/pipermail/gnupg-announce/2024q4/000488.html
Also released a *beta* of #gpg4win 5 see https://www.gpg4win.org/version5.html
Better handling of certificates and public keys
with #Gpg4win v4.4.0's improved crypto manager _Kleopatra_.
It also comes with #GnuPG v2.4.7 for Windows. Workflows that profit from several signatures on a file
profit as well.
https://gpg4win.org/version4.4.html <-- see what else is new.
Now THIS came in handy:
wsl-ssh-pageant
https://github.com/benpye/wsl-ssh-pageant
# How to use with #WSL
1. On the #Windows side start #Pageant (or compatible agent such as #gpg4win).
2. Run wsl-ssh-pageant.exe --wsl C:\my_path\ssh-agent.sock (max ~100 characters)
3. In WSL export the SSH_AUTH_SOCK environment variable to point at the socket
$ export SSH_AUTH_SOCK=/mnt/c/my_path/ssh-agent.sock
Tada! 
THIS is where I disagree...
You may think it's elitist, but if people are too lazy to learn even fundamentals like how to use #Tails then maybe they should just not do #tech at all?
I'll gladly teach #TechIlliterates but I won't waste my time on people that spread disinfo...
It's 2024: @tails_live / @tails has been out for over a decade and there are a shitload of guides ranging from written documentation to Zoomer-friendly TikTok-Style shorts on how to get started.
I don't expect people to do #airgapped pffline-PGP but with @thunderbird including #Enigmail and not requiring any external dependencies like the god-awful #GPG4Win stuff's easier than ever.
Same with #mobile: #Appls like @monocles / #monoclesChat are so easy, I've been able to onboard literal tech-illiterates remotely with few steps and simple instructions.
FOR THE LAST TIME:
*STOP MAKING EXCUSES TO JUSTIFY ESCALATING COMMITMENT TO EVIDENTLY BAD SOLUTIONS!"
Whereas with #SelfCustody of all the keys as well as #ReproduceableBuilds and real #decentralization, this would be evidently impossible even if all the devs wanted to comply honestly and not just because they could be held at gunpoint.
Compare that to #monocles where you do pay like €2 p.m. but in return get #standard #protocols like #IMAP, #SMTP & #XMPP and can pay anonymously and not have to provide any PII whatsoever!
Make of that what you will, but just like allowing flatearthers to roam freely without caretaker supervision doesn't make the world less round, so won't the facts change about #ITsec, #InfoSec, #OpSec & #ComSec.
Because all #centralized, #SingleVendor & #SingleProvider solutions are bad, and if they don't even allow for #SelfCustody then they are just a #grift to #scam tech-illiterates that don't know and/or don't care!
#Gpg4win ist ein Programmpaket für Windows, das alles mitbringt, um E-Mails mit #GnuPG zu verschlüsseln, unter anderem ein Add-on für Outlook.
Ansonsten bieten sich #Thunderbird oder #ClawsMail als E-Mail-Programme an, die gut geeignet sind, um E-Mails zu verschlüsseln.
Mittels #OpenPGP verschlüsselte E-Mails mögen altmodisch sein, aber sie erscheinen mir zunehmend sinnvoll.
New versions of #gnupg (2.4.5) and #gpg4win (4.3.1) have been released. See https://lists.gnupg.org/pipermail/gnupg-announce/2024q1/000482.html
The new #Gpg4win forum is waiting for you!

@mxmehl @harald I'd recommend using a different tool for #emails and #Outlook for everything else which is #groupware related.
If you can install your own software, you can try #Thunderbird. They got much worse after re-implementing #OpenGPG by themselves but it's still much better than Outlook, especially when #Gpg4win is involved otherwise.
Today it is to celebrate 25 years of #GnuPG a #FreeSoftware implementation of the '#OpenPGP and #CMS standards for #endtoendcrypto . For this GnuPG 2.4.0 is announced and #Gpg4win 4.1.0, see https://lists.gnupg.org/pipermail/gnupg-announce/2022q4/000477.html and https://lists.wald.intevation.org/pipermail/gpg4win-announce/2022/000099.html
Wozu soll ich E-Mails verschlüsseln, ich nutze doch TLS?
TLS schützt E-Mails lediglich während ihrer Übermittlung zwischen Servern oder Clients. Erlangen Unbefugte Zugriff auf ein E-Mail Postfach oder ein E-Mail Archiv, so gewährleistet eine Ende-zu-Ende Verschlüsselung dagegen weiterhin Vertraulichkeit; auch E-Mail-Provider können dann nicht auf den Inhalt von E-Mails zugreifen.
Unter anderem deshalb hat das #BSI die Projekte #GPG4Win und #Mailvelope unterstützt.
#Gpg4win 4.0.0 is a major upgrade of the official #GnuPG build for Microsoft Windows. Coming with the modern GnuPG 2.3 line for the first time. GnuPG provides a future-ready foundation for the secure exchange of data and mails over the next years, by implementing the upcoming draft of the #OpenPGP protocol and making the switch to better default algorithms. https://www.gpg4win.org/version4.html #EndtoEndCrypto #OpenPGP #OpenStandard #FreeSoftware
gnupg.org is self-sustainable now:
Not my cup of tea (windows), but I have just checked that I can successfully use my #nitrokey hardware key for establishing ssh connections with the excellent #putty, #mobaxterm and #gpg4win.

"GnuPG 2.2.21 and 2.2.22 (and Gpg4win 3.1.12) has an array overflow, leading to a crash or possibly unspecified other impact, when a victim imports an attacker's OpenPGP key, and this key has AEAD preferences. The overflow is caused by a g10/key-check.c error. NOTE: GnuPG 2.3.x is unaffected. GnuPG 2.2.23 is a fixed version."
