Definition
A digital certificate is an electronic credential that binds a public key to an identity (such as a website domain), usually issued by a trusted certificate authority.
Real-World Example
When you visit a bank site, your browser checks the site’s certificate to help confirm you are talking to the real domain, not an impostor.
