Jan 7, 2021 · 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.
ITU-T X.509 (formerly CCITT X.509) or ISO/IEC 9594-8, which was first published in 1988 as part of the X.500 directory recommendations, defines a standard certificate format . The certificate format in the 1988 standard is called the version 1 (v1) format.
The X.509 certificate is the international industry standard used to authenticate online identities and provide strong protection against devious imposters. From email communications to browser access, here’s how X.509 certificates support stable and secure online connections.
X.509 PKI Certificates Drive Enterprise Security. Since the introduction of the x509 standard for public key infrastructure (PKI) in 1988, x509 PKI and digital certificates have become a critical part of security for enterprises, governments and consumers the world over.
Jan 16, 2024 · A certificate provides a standardized and secure format to communicate with specific systems along with the attributes to help validate a key pair trust.
