In computing, a certificate is a digital document that uses cryptography to bind a public key with an identity. A certificate authority (CA) issues certificates, and every CA has a different certificate format. For example, the most common format for web server certificates is the X.509 standard. For a certificate to be trusted, it must be signed by a CA that is trusted by the computing device trying to verify the certificate. Certificate verification is an integral part of computing security, as it helps ensure that data comes from the expected source and has not been tampered with. For example, when you connect to a secure website, your web browser will use the site’s certificate to verify its identity before displaying any information from the site. Similarly, many email programs use certificates to verify the identity of email servers before sending or retrieving messages.
