GitHub sets new SSH security requirements for keys and clients
GitHub is phasing out older SSH cryptography, raising the minimum size for newly uploaded RSA keys and adding a post-quantum key exchange option.
What changed
The useful reading of this release is what it changes in the buying decision, not the announcement itself.
Why it matters
This matters most where deployment depends on permissions, sensitive data, auditability or regulated workflows.
Buyer takeaway
Buyers should verify the current rollout, plan eligibility and implementation details against the vendor documentation before changing a production workflow.
