Certifying Authorities

Certifying Authorities (CAs) are trusted organizations that issue digital certificates to confirm the identity of entities online, such as websites, companies, or individuals. These certificates ensure secure communications over the internet by validating that a public key belongs to the claimed owner. When you visit a secure website (indicated by "https"), your browser checks the site's certificate against a list of trusted CAs. If it’s valid, you can trust that you’re communicating with the legitimate site, helping to protect your data from fraud and cyber threats.
