Practical Public Key Infrastructure (PKI)

Public key infrastructure (PKI) is a framework that uses public key cryptography to automatically authenticate network devices and secure internet communication.
This book provides a practical overview of PKI concepts and protocols, with examples using OpenSSL - a widely adopted open-source library and toolkit available in many systems.
This book covers the following topics:
- Encoding methods used in PKI
- How hashing algorithms work
- Random number generation
- Key pair generation
- Authentication with public key algorithms
- Authentication with certificates
- Certificate validation methods
- Different certificate issuance methods
- How TLS works using PKI
- How S/MIME secures email
- How to generate cryptographic timestamps
- Basics of Hardware Security Modules (HSM)
- Basics of Trusted Platform Modules (TPM)
- FIPS Security Requirements for Cryptographic Modules
