authentication certificates

Authentication certificates are digital documents used to verify the identity of websites, servers, or individuals online. Think of them as a verified ID badge that confirms a site or user is legitimate and trusted. Issued by trusted organizations called Certificate Authorities (CAs), these certificates use encrypted information to establish a secure connection. When you visit a website with a valid certificate, your browser can confirm it's authentic, helping protect your data from hackers. In essence, authentication certificates build trust online, ensuring communications are private and secure.
