The clock is ticking on Q-Day, the looming yet unknown date when quantum computing will have the capacity to quickly and easily break the encryption keys that keep most internet communication safe.

Experts have known about the hypothetical risk of Q-Day since the 1990s. But Google recently warned that quantum computers may be able to hack some encrypted systems by 2029 — a timeline that drastically narrows the window to safeguard data that many cybersecurity specialists had previously predicted. The new estimate means that governments, companies and other entities may have far less time to prepare.

“It’s the day when people, perhaps adversaries, will have access to a quantum computer that can break cryptographic codes that are in use,” said Michele Mosca, cofounder and CEO of cybersecurity company evolutionQ.

Q-Day marks the moment a quantum computer gains enough resources and stability to crack conventional crytopgraphy. When that happens, every financial transaction, medical file, email, location history and crypto wallet protected by today’s commonly used algorithms could be unlocked by a machine capable of solving the complex math that currently keeps sensitive data secure.

At that game-changing turning point, “everything’s safe — safe, safe — and then suddenly it’s not safe. It’s a very drastic jump,” said Mosca, who is also a professor at the Institute for Quantum Computing at the University of Waterloo in Ontario.

Adversaries and bad actors may already be collecting encrypted data, with the intention of launching “harvest now, decrypt later” attacks. In this scenario, information is stolen, stored and then decrypted when a full-scale quantum computer is available, he added.

What’s changing in Proton Mail

Proton Mail has long used OpenPGP with ECC (Elliptic Curve Cryptography) and RSA (Rivest-Shamir-Adleman) keys to protect encrypted email, which remain secure against the computers of today. But large-scale quantum computers could break those schemes using algorithms such as Shor’s algorithm, a quantum computing technique designed to solve the kinds of mathematical problems that make RSA and ECC secure.

To prepare for that future, Proton Mail now supports encryption keys that withstand post-quantum cryptography (PQC). Find out how to enable post-quantum protection in Proton Mail with just a few simple steps.

Enabling PQC helps protect new encrypted emails going forward, and we plan to re-encrypt older emails in the future. As with existing keys, PQC keys can still be managed in familiar ways. You can generate more PQC keys later, and those keys can be marked obsolete or compromised just like RSA or ECC keys.

As part of this work, we are also adding support for OpenPGP v6, the newer framework that enables modern algorithm support, including post-quantum cryptography.

We are also standardizing quantum-safe encrypted email across the open email ecosystem, including with projects such as Thunderbird, so these protections can work between providers — not just within Proton — and help people stay safe no matter which email service they use.

He does and so will all the criminals.

Remember when someone stole the data of 10 million Optus customers?


Google AI:


In September 2022, hackers stole the personal data of approximately 10 million Optus customers, affecting roughly 40% of Australia’s population.  The breach exposed sensitive information including names, dates of birth, addresses, phone numbers, and passport or driver’s license details for millions of users.

Key details of the incident include:

Cause: Government officials, including Home Affairs Minister Clare O’Neil, stated the breach was caused by human error where an API was left exposed to the internet, contradicting Optus's claim of a sophisticated cyber attack.


Ransom and Apology: The attacker demanded a $1.5 million ransom in cryptocurrency but deleted the ransom notice and posted an apology online hours after leaking a sample of 10,000 records.


Legal Action: Optus faces a major class-action lawsuit from affected customers and civil proceedings from the Office of the Australian Information Commissioner (OAIC), which alleges the company failed to take reasonable steps to protect customer data.


Government Response: The Australian government announced reforms to cybersecurity laws and allowed the temporary sharing of sensitive data with financial institutions to help detect fraud against affected customers.

The Defense Advanced Research Projects Agency (DARPA) have estimated Bitcoin's encryption will be broken this side of 2028. Based on the speed of growth in quantum computing.

Q day will likely pass with the majority not realising, yet the ramifications will appear months and years afterwards.

Once Bitcoin is broken, miners will likely see the Bitcoin they just mined, disappear from their wallets. This sort of stuff.

Breaking most other encryption will probably occur a year after Bitcoin's.

Fun times are just around the corner.
