Policy
Enable post-quantum key agreement for TLS (obsolete)
Microsoft Edge
Policy overview
Key metadata and intent for this policy.
Supported OS tags: Windows7
OBSOLETE: This policy is obsolete and doesn't work after Microsoft Edge 146. This policy configures whether Microsoft Edge offers a post-quantum key agreement algorithm in TLS. This lets supporting servers protect user traffic from being decrypted by quantum computers. If you enable or don't configure this policy, Microsoft Edge offers a post-quantum key agreement in TLS connections. TLS connections are protected from quantum computers when communicating with compatible servers. If you disable this policy, Microsoft Edge won't offer a post-quantum key agreement in TLS connections. User traffic is unprotected from decryption by quantum computers. Offering a post-quantum key agreement is backwards-compatible. Existing TLS servers and networking middleware are expected to ignore the new option and continue selecting previous options. However, devices that don't implement TLS correctly may malfunction when offered the new option. For example, they might disconnect in response to unrecognized options or the resulting larger messages. These devices aren't post-quantum-ready and will interfere with an enterprise's post-quantum transition. If this issue is encountered, administrators should contact the vendor for a fix. This policy has been removed starting in Microsoft Edge version 147. Post-quantum key agreement is now enabled by default and cannot be disabled. Enterprises should work with device vendors to obtain fixes for proper post-quantum support.
