New Testing Tool Prevents Costly Post-Quantum Cryptography Migration Failures

Organizations migrating to post-quantum cryptography face hidden infrastructure breaks—certificate chains exceeding proxy size limits, signature bloat breaking TLS implementations—that typically only surface during live deployment. pqc-sandbox simulates these real-world failures on production endpoints before you commit to the migration, identifying critical issues like ML-DSA signatures that are 33× larger than ECDSA and routinely breach nginx's 8KB proxy limit. As quantum-resistant algorithms approach regulatory deadlines, pre-flight testing has shifted from optional to essential.
