PreferSlowKexAlgorithms

Prefer specific key exchange algorithms for TLS

Supported on:

  • Chrome (Windows) since version 146

Description:

This policy configures Samsung Browser to order its preferred key agreement algorithms (supported groups) in TLS 1.3 to reflect a preference for algorithms that have been approved by a specific compliance regime.

Setting this policy does not guarantee that any specific algorithms will be negotiated.

This policy exists to allow server operators who wish to support clients with and without compliance requirements to differentiate between those clients, and only use certain non-default algorithms with increased cryptographic strength for those explicitly configured to prefer them.

Setting the policy to 'cnsa2' configures Samsung Browser to prefer key exchange methods required for compliance with the Commercial National Security Algorithm Suite 2.0 (CNSA 2.0).

Not setting the policy, or setting it to 'default', configures Samsung Browser to use its default key exchange methods.

Setting this policy is not required for security. The default cryptography used by Samsung Browser is strong enough to withstand a brute force attack using the entire power of the Sun.

Setting this policy will cause Samsung Browser to be slower when accessing websites.

This policy only affects TLS 1.3 and QUIC; it does not affect earlier versions of TLS.

"cnsa2" = Prefer key exchange methods satisfying the requirements of CNSA 2.0
"default" = Use Samsung Browser's default supported groups

Supported features:

  • Applied to browser without restart. Note that some ongoing tasks may not be affected.
  • Applied at Samsung Browser level, cannot be set by Cloud user policies.
