I finally manage to encrypt the body trough ptyhon-gnupg ( warning their documentation is still in alpha stage. )

now, remain to encrypt the subject (ThunderBird compatible) if you have any clues I’m all ears

When time permit I will publish my code in a pastbin.

Wubba Lubba dub-dub**

indeed, but a lot of Linux distribution come with it :)
otherwise it’s installable.

instead of using a library I can directly use subprocess with gnupg but in both case it seem gnupg require to import the public key to the keyring !? I don’t want that.

Thank you all for your quick reactions !!

To summarize if I want to use the PDF built-in signing I will need to convert my OpenPGP into a X.509 cert otherwise I can simply use the OpenPGP file signing

I want to stick to the UNIX Philosophy especially:

Write programs that do one thing and do it well.

So I will use the OpenPGP signing tool :)

Thanks !

Has I found nothing, I’ve write a piece of code in Python 🐍 ! and compile it for Windows…

Thank you @Vilian@lemmy.ca Seem great, I’ll keep it for later :)

But not for what I need now, as

Mutt is a small but very powerful text-based mail client for Unix operating systems

and it’s a “full” client, I need just the SMTP functionality.

yes, it’s been years that I’m using CMD and as I’m planning get rid of windows there is no point for me to learn it.

OMG that too bad ! Lemmy that is federated and LOSS use github to track the bugs :/ Too bad I don’t have an account. So anyone, feel free to report this bug. Thanks.

ok I manage to send my post ! (it look like a lemmy bug… , do you know where to report it ? )

it seem that lemmy didn’t support the following

and weirdly, I can post here…

and a True Linux ! not one that has been “infected” with parts that do not respect The Four Essential Freedoms of Free Software

So avoid Ubuntu for example…

have a look a this video https://www.fsf.org/blogs/rms/20140407-geneva-tedx-talk-free-software-free-society/

And for a Linux distrio have a look at https://www.devuan.org 💓
