I wasn't aware of this, but they have an early pull request on working on #PQXDH and they also stated that they are working on:
"Ongoing futureproofing work includes Post Quantum resilience via Kyber post-quantum KEM and PQXDH key exchange, as well as support for Messaging Layer Security (MLS, RFC9420) for improved scalability for group encryption."

Постквантовая защита WhatsApp, новый Matrix 2.0 и PoW-задачи для входа на сайт
На Хабре уже упоминали , что протокол Signal получил постквантовую защиту, хотя в краткой новости не вдавались в детали. Но это действительно важное событие с учётом того, что количество пользователей этого протокола превышает 1 млрд человек за счёт WhatsApp. Signal применяется для криптографической защиты сессий в одноимённом мессенджере, в Google RCS , WhatsApp и др. Опенсорсный протокол можно использовать в любом ПО. Итак, что изменилось в криптографической подсистеме?

#Signal's post-quantum encryption, #PQXDH, has now been formally verified.
Hell yeah.

#signal : The #PQXDH #protocol is an extension of the #X3DH #protocol that establishes a shared #secret #key between three parties: Alice, Bob, and a server1 .
PQXDH provides #postquantum #forward #secrecy and a form of cryptographic deniability but still relies on the hardness of the discrete log problem for mutual authentication4 PQXDH is already supported in the latest versions of Signal's client applications and is in use for chats[…] #Further #reading -

Wow.
#Signal is strengthening its protocol and now has a way to resist #quantum computing attempts to break into your private messages.
I wonder what experts in #quantumcomputing like @rdviii think about this?
