What is an SSL Certificate? History
A certificate authority, often known as a certification authority (CA), is an organization that stores, signs, and provides digital certificates in the field of cryptography.
A digital certificate attests to the named subject of the certificate’s ownership of a public key. As a result, third parties (relying parties) are able to trust declarations made regarding the private key that corresponds to the certified public key.
A CA serves as a reliable third party who is respected by both the certificate’s subject (owner) and the party using it.
The format of these certificates is specified by the X.509 or EMV standard.
One particularly widespread usage for certificate authority is to sign certificates used in HTTPS, the secure surfing protocol for the World Wide Web. Another frequent application is the issuance of identity cards by national governments for use in document electronic signatures.
