Discover the definition of the term Digital Certificate presented by Les Assises de la Cybersécurité.

DIGITAL CERTIFICATE

A computer file signed by a certification authority, which uses this signature to guarantee that its owner is the person or entity it claims to be. Certificates are used to sign and encrypt documents and emails, to authenticate remote systems and to validate the identity of websites (the famous little green padlock on the web is based on a website certificate). Digital certificates are all based on the principle of asymmetric encryption, but they differ above all in the level of verification required by the Certification Authority before issuing them (from a simple email address to a face-to-face meeting).

It is technically possible to certify your own digital certificates. But it's like printing out your own diplomas: it looks nice, but it's not very useful.
