What is the use of X509 certificate?
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.
Is X509 a SSL certificate?
SSL/TLS X. 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 contain a public key and the identity of a hostname, organization, or individual.
What is X509 in SSL?
509 is a standard format for public key certificates, digital documents that securely associate cryptographic key pairs with identities such as websites, individuals, or organizations. First introduced in 1988 alongside the X. 509 certificates include: SSL/TLS and HTTPS for authenticated and encrypted web browsing.
What do you need to know about an X509 certificate?

What does a digital signature for X.509 mean?
A digital signature is an encoded hash (fixed-length digest) of a document that has been encrypted with a private key. When an X.509 certificate is signed by a publicly trusted CA, such as SSL.com, the certificate can be used by a third party to verify the identity of the entity presenting it.
Which is SSL certificate is signed by X.509?
For both administrative and security-related reasons, X.509 certificates are typically combined into chains for validation. As shown in the screenshot from Google Chrome below, the SSL/TLS certificate for www.ssl.com is signed by one of SSL.com’s intermediate certificates, SSL.com EV SSL Intermediate CA RSA R3.
Which is the X.509 certificate revocation list?
RFC 5280 profiles the X.509 v3 certificate, the X.509 v2 certificate revocation list (CRL), and describes an algorithm for X.509 certificate path validation. Common applications of X.509 certificates include: Need a certificate? SSL.com has you covered.
