Signal, the secure messaging app of choice for many, launched quantum-resistant encryption for its service in September with its protocol called <a href="https://arstechnica.com/security/2023/09/signal-preps-its-encryption-engine-for-the-quantum-doomsday-inevitability/2/" target="_blank" rel="noopener">PQXDH</a>.&nbsp;</p><p><a href="https://security.apple.com/blog/imessage-pq3/" target="_blank" rel="noopener">In a blog post</a>, Apple called this update the “most significant cryptographic security[...]
