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 for establishing secure connections with web-browsers and protecting sensitive data online.
What is an "X.509" Certificate?
X.509 is a set of international standards developed by the Internet Engineering Task Force (IETF) and National Institute of Standards and Technology (NIST) to enable users and servers to communicate securely over the Internet. It includes several protocols, such as SSL and TLS. HTTPS is a type network protocol which enables encrypted communication between a browser and a server.
Why should we use X509 certificates?
X509 employs a hierarchy-of-trust that allows the combination of different types of digital certificate to verify an entity's identity. It is required that each digital certificate be signed and issued by a Certificate Authority.
CAs sign the certificates of all others in their trust chain to guarantee that anyone they certify is trusted. These methods include public key encryption and certificate validity algorithms.
A CA also has the responsibility of implementing and managing a set of rules to ensure that its issued certificates are valid and secure. 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
CA's use public key encryption and recursive encoding to verify a certificate. 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 creates a new certificate, it is required to provide a unique identifier for the certificate. 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. They may or may not work with certain programs or web browsers, depending on the file format.
What are X509 Extensions?
Multiple extensions can be included in X509 certificates that define extra attributes. These additional attribute are used to maintain a certificates hierarchy, revocations or other information on the 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 the name of X509, certificates can be saved in a number of different formats. X509 Certificates are stored by most organizations in DER or PEM files. DER is a common encoding system that's compatible with most web-browsers and other software.
