Certificate Authorities
Who issues certificates.
What Is a CA?
A Certificate Authority (CA) is a trusted organization that issues and digitally signs certificates.
When a CA signs a certificate, it is asserting: we have verified this identity, and you can trust this public key.
Why CAs Matter
Browsers and operating systems ship with a built-in list of trusted root CAs.
Because everyone already trusts these roots, a certificate signed by them is automatically trusted without manual configuration.
