What is X509?

X.509 is a standard defining the format of public key certificates. X.509 certificates are used in many internet protocols, including TLS/SSL, HTTPS, S/MIME, and IPsec, to establish secure communication channels. They bind an identity to a public key, allowing verification of the sender's identity and encryption of data.
