The new company received licenses to key cryptographic patents held by RSA and a time limited non-compete agreement. The new company served as a certificate authority (CA) — a role it still fulfills — and its initial mission was "providing trust for the Internet and Electronic Commerce through our Digital Authentication services and products." VeriSign now has more than 3,000,000 certificates in operation for everything from military to financial services and retail applications, making it the largest CA behind the encryption and authentication on the Internet, which most people recognize as the small padlock icon in their Web browser when shopping online. VeriSign is well known for the VeriSign Secured Seal, which is an outward expression of a Web site's authentication and encryption commonly posted to VeriSign SSL Certificate customers' Web sites.
