OpenSSH 10.6 switches on post-quantum signatures, older keys must be replaced
Original: OpenSSH 10.6 enables a post-quantum signature algorithm, so experimental keys need replacing
OpenSSH 10.6 has been released with a post-quantum signature algorithm enabled by default. The change means keys generated with earlier experimental implementations of the algorithm will need to be replaced, and administrators are being urged to regenerate keys when upgrading. The release marks another step in the migration toward quantum-resistant cryptography across critical internet infrastructure.
Why now: System administrators are discussing the upgrade because it forces key replacement in production SSH setups.
