Post-Quantum Encryption Plans?

Need Answer

Is Maibox.org working on Post-Quantum Encryption? If so, when does the team hope to roll this feature out? As for why it matters: https://tuta.com/blog/world-quantum-day

"While quantum computing has the potential to bring about the next impressive digital revolution, we must not ignore the threat that comes along with it: breaking encryption. Fortunately, quantum-resistant encryption is here to protect us from this threat...In addition to big tech, governments around the world - including the U.S., China, and the EU - are ramping up their R&D budgets for quantum computing, making the probability of a quantum breakthrough in the near future ever more likely...Powerful quantum computers, namely quantum computers with about 20 million physical qubits, will be capable of breaking widely used encryption algorithms such as RSA and ECC, according to the German national cyber security agency BSI. As consequence, once powerful quantum computers exist, currently used asymmetric encryption, for instance, PGP used for email encryption, will not be safe to use anymore. Even worse: powerful adversaries around the world already scoop up encrypted data shared via the internet with the aim of decrypting it once they have access to quantum computers. For this reason, we need quantum-resistant cryptography now – not in five or fifteen years."

Meanwhile, on the other side of town...

Proton Mail now supports post-quantum encryption for all users, including free accounts

"Proton Mail has enabled optional post-quantum protection on all its plans, including free accounts. Once activated, users can generate new post-quantum-ready encryption keys to secure emails against both present-day threats and potential future attacks by quantum computers. This update responds to concerns that large-scale quantum computing could eventually undermine traditional cryptographic methods such as RSA and elliptic curve cryptography.

Building on this advancement, Proton Mail is introducing support for OpenPGP version 6. The updated framework allows the use of modern encryption algorithms, including those designed for resistance against quantum-based decryption techniques. These upgrades facilitate secure communication for both personal and business users.

While transitioning to these quantum-safe keys, users can continue familiar key management practices, such as generating new keys, and marking keys as obsolete or compromised, just as with legacy RSA or elliptic curve cryptography keys. However, activating post-quantum protection only impacts new encrypted messages going forward; existing emails in the mailbox are not re-encrypted at this time.

Proton is also collaborating with other email providers and clients, such as Thunderbird, to promote cross-provider standards for quantum-safe encrypted email. This step aims to help users maintain secure communication, regardless of their chosen email service."
