Proton is building quantum-safe PGP encryption for everyone

You might have heard about quantum computers, a futuristic kind of computer that can perform certain operations far faster than today’s machines. You might have also heard that quantum computers will soon break encryption and expose everyone’s data.

In reality, quantum computers are already here, but they’re still pretty basic. Quantum computing technology is years or decades away from breaking current encryption standards, and its future applications are hypothetical. For now, your data is safe.

Even so, we take the potential threat seriously. Proton is not uniquely affected by this challenge, but we are uniquely equipped to confront it. We have a decade of experience developing and maintaining innovative open source cryptography(new window). Our encrypted services protect the data of over 100 million accounts, with Proton Mail as the largest end-to-end encrypted email provider in the world. Many other services are built on the cryptographic libraries that we write and maintain. Because the security of our users and their data is our top priority, we’re always on the alert for new threats. Quantum computers are one of them. ...
