The original title is "Add a post-quantum readiness gate to your CI in 5 lines"

Short summary

Post-quantum cryptography defends against 'harvest now, decrypt later' attacks on today's encrypted data. This free GitHub Action scans repos for quantum-vulnerable crypto, grades readiness A–F, and gates PRs on classical weaknesses (MD5, RC4, 3DES). Deploy in 5 YAML lines; CNSA 2.0 and DORA compliance requires inventorying quantum-vulnerable key establishment by Jan 2025.

• •Quantum computers threaten RSA/ECDSA/TLS encryption retroactively: adversaries capturing encrypted traffic today can decrypt it once quantum computers exist
• •Free GitHub Action emits CBOM, SARIF alerts, grades post-quantum readiness; implement with 5 lines of YAML config in CI/CD
• •CNSA 2.0 (US federal suppliers), DORA (EU financial entities Jan 2025), and NIS2 now mandate cryptographic bill of materials and risk management
