A Public Key Infrastructure (PKI) itself does not perform encryption; rather, it provides the framework for managing digital certificates and keys that facilitate encryption. PKI enables secure communication by allowing users to encrypt data using the recipient's public key and ensures the integrity and authenticity of the data through digital signatures. The actual encryption and decryption processes are performed by the cryptographic algorithms that utilize the keys managed by the PKI.
It stands for Public Key Infrastructure. It has to do with security and data encryption.
PKI must use asymmetric encryption because it is managing the keys in many cases. This implies the use of public and private key pairs, which is asymmetric.

DOD PKI tokens are security devices used by the Department of Defense (DoD) to provide secure authentication and encryption for accessing sensitive information and systems. These tokens typically store digital certificates and private keys, enabling users to authenticate their identity and establish secure communications. They are part of the DoD's Public Key Infrastructure (PKI), which ensures the integrity and confidentiality of data within military and government operations. These tokens help enhance cybersecurity by requiring strong, multifactor authentication methods.
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.
Public Key Infrastructure (PKI) in an integrated system of software, encryption methodologies, protocols, legal agreements, and third-party services that enables users to communicate securely an protect information assets.
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.
Firstly you require a program to do the encryption and ensure your system is compatible. Many programs are available that offer this capability and the steps would vary.
A critical concept common to all PKIs is the use of digital certificates issued by a trusted entity, known as a Certificate Authority (CA), to validate the identities of users and devices. These digital certificates contain public key information and are used to establish secure communications through encryption and digital signatures. Trust in the PKI is based on a hierarchical system where higher-level CAs vouch for the identities of lower-level CAs, creating a chain of trust.

You be referring to a CAC Card. This was a common access card, also used for computer security by the DoD and military that doubles as an ID Card in some cases. It's used for PKI (Public Key Infrastructure) encryption key holding as well in some cases.
