What is a digital certificate?

A digital certificate or identity key is normally issued by a web certificate authority and contains the sender’s public key verifying that the certificate is authentic and that the website in question is legitimate.

How does a digital certificate work?

Trusted certificates are usually stored on the client software, such as a web browser.

Certificate authorities and the digital certificates they issue are used to prevent “man-in-the-middle” attacks, in which a malicious party intercepts traffic heading to a server and pretends to be the intended receiver.
