• Google Cloud now offers PQC algorithms to digital signatures
• The move comes as part of Google Cloud Quantum-Safe Roadmap
• The feature is available in preview now, with multiple PQC changes coming

Google Cloud has taken an extra step to secure its platform from the threat of Quantum Computing for Public-Key Cryptography by announcing the availability of quantum-proof digital signatures in Preview in Google Cloud Key Management Service (KMS).

Theoretically, quantum computers will be able to crack most modern encryption algorithms within hours, but the viability of such a system is still at least a decade of most expert estimates.
