A digital certificate called an x509 certifies that the public key contained in it belongs to a particular user, computer, or service. These certificates are used for establishing secure connections with web-browsers and protecting sensitive data online.
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 a type network protocol which enables encrypted communication between a browser and a 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. This is done by a number of methods, such as public-key cryptography and certificate verification algorithms.
A CA's other responsibility is to implement and maintain a set of guidelines that will ensure its issued certificate are valid and secure. These rules also include the use of revocations lists to remove any certificates that do no meet the CA's requirements and the disavowal of any CAs who are non-compliant or compromised.
Certification Path Verification
CAs apply several verification techniques including public key cryptography and recursive encode to validate certificates. 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.
A CA must give a unique certificate ID when it issues a certification. This can be an email address or ID number.
These identifiers can be found in the contents of files such as DER and PEM. These files are compatible or not with certain applications and web browsers depending on their format.
What are X509 Extended Certificates?
X509v3 certificate extensions may 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 are useful for a variety of purposes, including role-based security and access control.
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 encoding is a widely used encoding that can read by some web browsers. However, it's not compatible in all applications.
