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 an "X.509" Certificate?
X.509 standards are a collection of international standards created by the Internet Engineering Task Force and National Institute of Standards and Technology. They enable servers and users to communicate safely over the Internet. It contains several protocols like SSL and 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?
X509 is based on a trust hierarchy that allows for different types digital certificates to be used together to verify identity. Each certificate must be signed by the Certificate Authority (CA).
CAs must sign all other certificates to ensure that anyone whose identity they verify will be trusted. The CAs do this by using a variety verification methods including public key cryptography, certificate validation algorithms and other techniques.
A CA must also implement and manage a set rules in order to ensure that the certificates it issues are secure and valid. These rules include applying revocation lists to remove certificates that do not meet their requirements and disavowing any non-conforming or compromised CAs.
Certification Path Verification
To validate a certificate, a CA will apply a series of verification techniques to it, including recursive encoding and public key cryptography. In addition, the CA must adhere to a certification pathway validation algorithm. It involves recursively incorporating intermediate certificates. These certificates are then signed with other certificates and finally reach an end-entity certifcate.
When a CA issuing a certifcate, it must provide an unique certificate identifier which is unique to the certifcate. This can be an email address or ID number.
These identifiers are typically stored as part of a certificate's contents in files, such as DER or PEM. Depending on how the files are formatted, they may be compatible with some applications or web-browsers.
What are X509 certificate extensions?
These extensions define additional attributes. These additional attributes allow you to manage a certification's hierarchy, list of revocations, or any other information regarding the holder. These attributes can also be used to control access based on roles and for other purposes.
How do X509 certificates get stored?
Despite their names, X509 certifcates can be kept in a range of formats. Most organizations and companies store their certificates as DER or PEM. DER, a popular encoding format that is compatible with some software and most web browsers but not all, can be read.
