Expect-CT vs HPKP

Developers should implement Expect-CT to improve security for HTTPS-enabled websites, particularly in environments where certificate misissuance is a concern, such as high-risk financial or government sites meets developers should learn about hpkp primarily for historical context in web security, as it was used to enhance https by preventing certificate authority compromises or rogue certificates. Here's our take.

Expect-CT

Nice Pick

Developers should implement Expect-CT to improve security for HTTPS-enabled websites, particularly in environments where certificate misissuance is a concern, such as high-risk financial or government sites

Pros

• It is crucial for compliance with modern security standards like those from the CA/Browser Forum, and helps prevent man-in-the-middle attacks by ensuring certificates are publicly logged and monitored
• Related to: https, ssl-tls

Cons

• Specific tradeoffs depend on your use case

HPKP

Developers should learn about HPKP primarily for historical context in web security, as it was used to enhance HTTPS by preventing certificate authority compromises or rogue certificates

Pros

• It was relevant for high-security applications like banking or government sites, but its deprecation means modern alternatives like Certificate Transparency and Expect-CT headers are now preferred for similar security goals
• Related to: https, tls

Cons

• Specific tradeoffs depend on your use case

The Verdict

Use Expect-CT if: You want it is crucial for compliance with modern security standards like those from the ca/browser forum, and helps prevent man-in-the-middle attacks by ensuring certificates are publicly logged and monitored and can live with specific tradeoffs depend on your use case.

Use HPKP if: You prioritize it was relevant for high-security applications like banking or government sites, but its deprecation means modern alternatives like certificate transparency and expect-ct headers are now preferred for similar security goals over what Expect-CT offers.

The Bottom Line

Expect-CT wins

Developers should implement Expect-CT to improve security for HTTPS-enabled websites, particularly in environments where certificate misissuance is a concern, such as high-risk financial or government sites
