An X. 509 certificate is a digital certificate based on the widely accepted International Telecommunications Union (ITU) X. 509 standard, which defines the format of public key infrastructure (PKI) certificates. They are used to manage identity and security in internet communications and computer networking.

An X. 509 certificate binds an identity to a public key using a digital signature. A certificate contains an identity (a hostname, or an organization, or an individual) and a public key (RSA, DSA, ECDSA, ed25519, etc.), and is either signed by a certificate authority or is self-signed.

The x509 utility can be used to sign certificates and requests: it can thus behave like a "mini CA". this option causes the input file to be self signed using the supplied private key.
