A digital certificate is an electronic document used to prove the ownership of a public key, often as part of a public key infrastructure (PKI). It typically contains information about the key, the identity of its owner, and the digital signature of the certificate authority (CA) that issued it. Digital certificates are essential for secure online communications, enabling encryption and authentication in various applications like SSL/TLS for websites. They help ensure that data exchanges are secure and that the parties involved are who they claim to be.
