Verification of security mechanisms complementary to HTTPS.
What is HTTPS+ Checker?
HTTPS+ Checker is a Firefox add-on that allows you to quickly check if a website has HSTS, HPKP, DANE / TLSA, and DNSSEC security mechanisms in place. It verifies these complementary security measures without validating if your session uses them.
The extensions quickly check if the website has HSTS, HPKP, DANE / TLSA and DNSSEC (but do not validate if your session uses them).
HTTPS+ Checker is risky to use as it requires a number of sensitive permissions that can potentially harm your browser and steal your data. Exercise caution when installing this add-on. Review carefully before installing. We recommend that you only install HTTPS+ Checker if you trust the publisher.
HTTPS+ Checker has earned a fairly good reputation and likely can be trusted.
