OpenSSH 10.6 enables a post-quantum signature algorithm, so experimental keys need replacing
OpenSSH 10.6 was released October 6 and introduces support for a post-quantum signature algorithm, requiring users with experimental keys to replace them. The project announced a faster release cadence to deliver security fixes more rapidly, and noted an increase in security reports discovered through artificial intelligence (AI) models and AI-assisted analysis.
Why it matters: OpenSSH users running experimental post-quantum keys must update and regenerate keys to maintain compatibility and security posture as the algorithm transitions from experimental status.
