Too Long; Didn't Read
A digital certificate is a data file that binds a publicly known cryptographic key to an organization. Mozilla (stylized as moz://a) is a free software community founded in 1998 by members of Netscape.com. Digital certificates contain information about an organization, such as the common name (e.g., mozilla.org), the organization unit (e.g., Mozilla Corporation), and the location (e). Digital certificates are most commonly signed by a certificate authority, attesting to the certificate's authenticity.
