Show HN: An open source tool that checks for post-quantum crypto
A new open-source tool has been developed to assess the readiness of systems for post-quantum cryptography. This tool helps verify whether endpoints support post-quantum algorithms, addressing the growing threat posed by quantum computers to current encryption methods. Governments are pushing for a transition to post-quantum cryptography, making such tools increasingly essential for cybersecurity.
- ▪The tool checks TLS, SSH, and VPN endpoints for post-quantum cryptographic algorithms.
- ▪It provides a binary verdict on the readiness of the endpoints, indicating whether they are vulnerable to future quantum threats.
- ▪Governments like the U.S., UK, and EU are mandating the shift to post-quantum cryptography to enhance security.

Opening excerpt (first ~120 words) tap to expand
PQC Tools Post-Quantum Cryptography readiness scanner and connection monitor. Quantum computers will soon break the RSA and elliptic-curve cryptography that protects almost all internet traffic. Adversaries are already harvesting encrypted data today to decrypt later — the "harvest now, decrypt later" threat. Governments are now mandating the shift to post-quantum cryptography: the U.S. has set aggressive timelines through NSA CNSA 2.0 and NIST standardization of ML-KEM and ML-DSA; the UK NCSC requires government and critical national infrastructure to begin PQC migration; and the EU's ENISA guidance and NIS2 framework are pushing operators to audit and upgrade their cryptographic estates. These tools give you a fast, automated way to aid verifying whether your endpoints are ready.
