Overview
X.509 is a ITU-T standard for a public key infrastructure (PKI).
X.509 specifies, amongst other things, standard formats for public key certificates, certificate revocation lists, attribute certificates, and a certification path validation algorithm.
X.509 is a common certificate format that can be managed by JDK's keytool.
