Google Trust Services announced that a number of Google services will move from RSA to ECDSA leaf certificates by default in Q2 2026. ECDSA is not quantum-safe; under standard resource estimates it falls to a smaller quantum computer than RSA-2048. The move still makes sense: TLS migrates in layers, post-quantum key exchange is already the default in major browsers, and certificate migration is blocked on signature sizes and ecosystem constraints that…
