What Is An X509 Certificate? (TOP 5 Tips)

What do you need to know about a X.509 certificate?

  • No matter its intended application (s), each X.509 certificate includes a public key, digital signature, and information about both the identity associated with the certificate and its issuing certificate authority (CA): The public key is part of a key pair that also includes a private key.

What is a x509 certificate used for?

509 is a standard defining the format of public-key certificates. X. 509 certificates are used in many Internet protocols, including TLS/SSL, which is the basis for HTTPS, the secure protocol for browsing the web. They are also used in offline applications, like electronic signatures.

What is the difference between SSL and x509 certificate?

509 certificates are digital files that are used for Secure Sockets Layer (SSL) or Transport Layer Security (TLS). An SSL/TLS certificate is one of the most popular types of X. 509 certificates or a type of public-key certificate which uses the X. 509 standard.
