The public key is comprised of a string of random numbers and can be used to encrypt a message. Leveraging ASN, the X.509 certificate format uses a related public and private key pair to encrypt and decrypt a message. The X.509 standard is based on an interface description language known as Abstract Syntax Notation One (ASN.1), which defines data structures that can be serialized and deserialized in a cross-platform way. What enables this is that public keys can be distributed widely and openly without malicious actors being able to discover the private key required to decrypt the message. The PKI architecture is so scalable that it can secure billions of messages exchanged daily by organizations over their own networks and across the internet. Scalability - An additional benefit of this certificate-based approach to identity is scalability.When a certificate is signed by a trusted CA, the certificate user can be confident that the certificate owner or hostname/domain has been validated, while self-signed certificates can be trusted to a lesser extent as the owner doesn't go through any additional validation before issuance. It has been signed by a publicly trusted issuer Certificate Authority (CA), like Sectigo, or self-signed.A public key belongs to the hostname/domain, organization, or individual contained within the certificate.The key usage architecture lets certificates verify that: This level of trust is established both by how X.509 certificates work and by how they are issued. For example, without these, we wouldn't be able to trust that is actually Amazon's website. As the foundation for all digital identities, X.509 certificates are everywhere and are essential to every connected process from websites to applications to endpoint devices and online documents. Trust - Digital certificates allow individuals, organizations, and even devices to establish trust in the digital world.

Now version 9 is the current version of the standard, having been defined in October 2019.Īdditionally, the Internet Engineering Task Force (IETF) public-key infrastructure working group, known as PKIX, adapted the X.509 v3 certificate standard in the development of its own Internet X.509 Public Key Infrastructure Certificate and Certificate Revocation List (CRL) Profile standard (RFC 5280).

In 1996, version 3 of the standard provided a major update with the addition of multiple extensions that are still used today to support the expansion and new applications of internet use. Looking to formalize the rules for certificate issuance, the Telecommunication Standardization Sector of the ITU (ITU-T) developed a hierarchical system for distinguished names that followed the electronic directory service rules for X.500 and was inspired by the systems used to assign telephone numbers globally but applied to the more flexible organizational requirements of the Internet. The first version of the X.509 standard was published back in 1988.

But the X.509 protocol is also applied to code signing for application security, digital signatures, and other critical internet protocols. The most common use case of X.509-based PKI is Transport Layer Security (TLS)/Secure Socket Layer (SSL), which is the basis of the HTTPS protocol, which enables secure web browsing. Applied to cryptography, the public and private key pair is used to encrypt and decrypt a message, ensuring both the identity of the sender and the security of the message itself. One of the structural strengths of the X.509 certificate is that it is architected using a key pair consisting of a related public key and a private key.

They are unobtrusive and ubiquitous, and we encounter them every day when using websites, mobile apps, online documents, and connected devices. They are used to manage identity and security in internet communications and computer networking.

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.
