Category: security

Tags: post-quantum, tls, ssh, measurement, cryptography, distributed-probes

Score: 6.3/10 (Innovation: 7, Technical: 6, Documentation: 5, Utility: 6)

Witnessory provides signed, recomputable measurements of post-quantum cryptography adoption across the internet's top sites and SSH servers, using distributed probes to ensure verifiability. The project combines measurement infrastructure with a cryptographic trust model (signed readings and deterministic aggregation) to make adoption statistics auditable rather than trust-based.

Target audience: security researchers, devops engineers, cryptography practitioners, policy analysts
