What Does Digital Certificate Mean?
A digital certificate authenticates the Web credentials of the sender and lets the recipient of an encrypted message know that the data is from a trusted source (or a sender who claims to be one). A digital certificate is issued by a certification authority (CA).
Techopedia Explains Digital Certificate
A person (sender), who is sending an encrypted message may obtain a digital certificate from a CA to ensure authenticity. The CA issues the digital certificate with the applicant’s public key, along with other information such as holder name, serial number, date of expiration and a digital CA signature. It also issues its own public key in the public domain via the Web.
