Why Signal’s post-quantum makeover is an amazing engineering achievement

Signal Messenger LLC has made significant strides in making the Signal Protocol fully quantum-resistant, protecting communications from potential quantum computing threats. While many organizations are hesitant to invest in quantum-resistant algorithms due to cost and uncertainty, Signal's engineering team has successfully upgraded the protocol to withstand quantum attacks. The complexity and precision required for this achievement are compared to that of a fine Swiss timepiece, showcasing the team's exceptional problem-solving skills. This development marks a major milestone in ensuring secure end-to-end encryption for private chat apps like Signal Messenger.
