What does CA stand for?

CA stands for Certificate Authority, the company issuing the SSL certificate.

A certificate authority (CA) is the trusted entity that issues electronic documents that verify a digital entity’s identity on the Internet. The electronic documents, which are called digital certificates, are an essential part of secure communication and play an important part in the public key infrastructure (PKI). Certificates typically include the owner's public key, the expiration date of the certificate, the owner's name and other information about the public key owner. Operating systems (OSes) and browsers maintain lists of trusted CA root certificates to verify certificates that a CA has issued and signed.

Although any entity that wants to issue digital certificates for secure communications can potentially become their own certificate authority, most e-commerce websites use certificates issued by commercial CAs. Typically, the longer the CA has been operational, the more browsers and devices will trust the certificates a CA issues.  Ideally, certificates are backwards compatibile with older browsers and operating systems, a concept known as ubiquity.
