An x509 certificate is a digital certificate used to verify that a public key belongs to the user, computer or service identity contained within it. These certificates are used to establish secure connections with web browsers and protect sensitive data online, relying on the widely accepted X.509 PKI (Public Key Infrastructure) standard to do so.
What is a X.509 Certification?
X.509, a set of standards international standards developed jointly by the Internet Engineering Task Force and the National Institute of Standards and Technology, enables users and servers communicate securely via the Internet. It includes protocols like SSL or TLS. HTTPS is built on TLS, a type of protocol that allows encrypted communications between a website and its server.
Why should we use X509 certificates?
It uses a hierarchy to allow different types of certificates to be combined to verify an entity. Each certificate must be signed by the Certificate Authority (CA).
CAs sign the certificates of all others in their trust chain to guarantee that anyone they certify is trusted. They accomplish this by using various verification methods such as public key cryptography or certificate validation algorithms.
A CA has to implement and manage rules for the security and validity of certificates issued by it. These rules may include applying revocations to certificates that fail to meet their requirements or disavowing any CAs that are not conforming.
Certification Path Verification
CAs will use a variety of verification techniques on a certificate to validate it. These include recursive cryptography and encoding. The CA must also follow a certification-path validation algorithm. This involves recursively including intermediate certificates that will be signed by another certificate, and eventually reaching a final entity certificate.
When a CA creates a new certificate, it is required to provide a unique identifier for the certificate. This can include a number, an email, or a person's name.
These identifiers can be found in the contents of files such as DER and PEM. Depending on the format of the files, they may or may not be compatible with certain applications or web browsers.
What are X509 Certificate Extensions?
Multiple extensions can be included in X509 certificates that define extra attributes. These attributes can be used to manage the hierarchy of a certificate, revocation list, or information about the certificate holder. These attributes may be used in a number of ways, such as for role-based access controls and other purposes.
How Do X509 Certificates Get Stored?
Despite their names, X509 certifcates can be kept in a range of formats. Currently, most companies and organizations store their X509 certificates in either DER or PEM files. DER is a popular encoding scheme that can be read and understood by many web browsers, although it may not work with all software.
