Certification Authorities (CAs)

A Certification Authority (CA) is an organization that issues digital certificates to verify the identity of websites, individuals, or organizations online. These certificates function like digital passports, confirming that a website is legitimate and secure. When you visit a secure site (https), your browser checks the site's certificate issued by a trusted CA. If the certificate is valid and trusted, your connection is encrypted, protecting your data. CAs play a vital role in establishing trust and security on the internet by ensuring that digital identities are authentic and trustworthy.
