One can receive a PKI certificate, or a public-key infrastructure certificate, is by digitally signing and publishing the public key bound to a given user.
PKI is a set of procedures in order to establish a secure information. The six components are: Revocation, Certificate Authority, Certificate Publishing, Registration Authority, PKI aware application, Certificate Management System.

PKI or Public Key Infrastructure
A root certificate is indeed the foundational certificate issued by a Certificate Authority (CA), serving as the trusted anchor for a public key infrastructure (PKI). It is used to verify the authenticity of other certificates issued by the CA, creating a chain of trust. Root certificates are typically embedded in operating systems and browsers to facilitate secure communications over the internet. Their security is paramount, as compromising a root certificate can undermine the integrity of the entire PKI.

system for encrpting sensitive information
Public Key Infrastructure (PKI) operates by using a combination of hardware, software, policies, and procedures to manage digital certificates and public-key encryption. It involves a trusted Certificate Authority (CA) that issues digital certificates to verify the identity of entities, allowing secure communication. Users generate a pair of keys: a public key, which is shared widely, and a private key, kept secret. PKI ensures the integrity, authentication, and non-repudiation of data through cryptographic techniques, enabling secure transactions over unsecured networks.
A VeriSign Certificate, now part of DigiCert, is a type of digital certificate used to secure online communications and authenticate the identity of websites. It utilizes public key infrastructure (PKI) to encrypt data, ensuring secure connections for activities like online transactions. By verifying the identity of the certificate holder, it helps establish trust between users and websites. Organizations often use VeriSign Certificates to enhance their security posture and instill confidence in their customers.
