Signal deploys the SPQR triple ratchet
Signal extends its earlier PQXDH work with a post-quantum ratchet, closing the gap for long-lived conversation state.
QCrypt Watch follows the standards, national mandates, funding and deployments that decide when and how the world replaces classical public-key cryptography, and how much time your data actually has.
Until RSA and ECC are disallowed for US federal use
National programs with published migration timelines

Standards decisions, regulation, funding and real-world deployment, filtered for signal.
Signal extends its earlier PQXDH work with a post-quantum ratchet, closing the gap for long-lived conversation state.
Buyers increasingly prioritize the ability to swap algorithms over any single algorithm choice, reshaping vendor roadmaps across PKI and HSM portfolios.
Government and defense contracts increasingly specify long-term confidentiality horizons, forcing suppliers to answer for data captured today and decrypted later.
Several tier-one institutions begin hybrid key exchange trials on interbank links, citing harvest-now-decrypt-later exposure on decades-long confidentiality requirements.
Hybrid X25519MLKEM768 key agreement crosses a visible adoption threshold on the public internet, driven by default-on browser support.
A revised analysis lowers the estimated qubit count needed for Shor's algorithm against RSA-2048, tightening credible Q-Day windows without changing near-term feasibility.
