#GlobalEncryptionDay

The videos of the Encryption Summit 2025–organized as part of #GlobalEncryptionDay–are now all online.

In most conversations the criticality of encryption and system security for national security came up. Panelists with prosecution and enforcement background argued that alternatives are available and working.

It's easier than ever to set up #GPG for email #encryption , even simpler than when @fsf wrote this handy guide!

It's still a great starting point and walks through the basics. Maybe it's time for you to take a fresh look at good "old-fashioned" GPG / PGP and try it out on #GlobalEncryptionDay 😎

HΛPPY 🔒 #GlobalEncryptionDay !!1!

We often rely on company's back-end for encryption. But there is a way to do it directly on our systems by using GPG. Thus, encrypting the content before it is sent.

the FSF made a nice Email Self-Defense Guide:

You can use it in thunderbird, terminal, emacs, shell you name it

Today we join @internetsociety and peers around world to celebrate #GlobalEncryptionDay.

The right to private conversation is foundational to freedom and democracy, and MUST be protected.

Here in🇨🇦, that means we must STOP #BillC2 and FIX #BillC8!

It's global encryption day!

Encryption is such a critical tool to protect your personal information, but in some places around the world it's under threat.

We need to remind people and especially our governments that we all need strong, encryption without backdoors to stay safe on the internet.

The existence of strong, public-key cryptography is always a reminder to me that maths can be on the side of people. Imagine if privacy was a mathematical impossibility instead of an inevitability!
