GitHub removing legacy SSH algorithms, requiring larger RSA keys

Wed, 23 Sep 2026 15:14:55 +0000

Platform/SRE — Plan: Review any SSH keys used for infrastructure automation against GitHub repos (deploy keys, Ansible/Terraform git sources) to confirm they meet the new algorithm and minimum RSA key-size requirements before the removals take effect; no hard deadline is published yet.
CI/CD — Plan: Audit SSH deploy keys and runner SSH credentials used to pull private repos or push artifacts via GitHub to ensure they use accepted algorithms and sufficiently large RSA keys; schedule rotation for any that don’t comply before the removal lands.
Leader — Skip
