Browsers sometimes won’t load page because there’s problem with certificate. What are these certificates and who issues them? Why it’s dangerous to open page with invalid one?
In: Technology
Certificates are basically ID’s for websites. They are issued by a certificate authority that is trusted by other organizations, like the DMV with your driver’s license.
Your browser knows what companies it can trust to issue certificates, and can follow a path back to validate that a certificate is legit or not.
The issue with opening page with invalid certs is that if the cert is invalid, you have no way to know whether or not the site you are trying to visit is actually a legit site or not.
