A digital certificate is a file or electronic password that proves the authenticity of a device, server, or user through cryptography and the public critical infrastructure (PKI). Digital certificate authentication helps organisations ensure that only trusted devices and users can connect to their networks. It’s also used to verify the authenticity of a website to a web browser, also known as a secure sockets layer or SSL certificate.
A digital certificate contains identifiable information, such as a user’s name, company, department, and device’s Internet Protocol (IP) address or serial number. It includes a copy of a public key from the certificate holder, which must be matched to a corresponding private key to verify it is real. A public-key certificate is issued by certificate authorities (CAs), which sign certificates to verify the identity of the requesting device or user.
