Pki: The Complete Cross-Platform Practitioner's Guide: Public-Key Infrastructure for Windows, Linux, macOS, and Mobile

By Amit Jagtap

Everything you need to design, deploy, and run public-key infrastructure - on every platform your organization actually uses.
Public-key infrastructure is the quiet foundation under every secure system: HTTPS, smartcard logon, code signing, corporate Wi-Fi, VPNs, signed containers, and encrypted email all rest on certificates and the trust behind them. When PKI works, it is invisible. When it breaks, everything fails at once. This book gives you the concepts and the hands-on skill to make sure it works - and keeps working.
PKI: The Complete Cross-Platform Practitioner's Guide is a single, practical reference that takes you from first principles to production operations across Windows, Linux, macOS, and mobile. It does not stop at theory: every concept is paired with a diagram, real commands, and the output you should expect to see.
Inside you will master:
- The trust problem, cryptography, and X.509 certificates - explained clearly from the ground up
- Certificate authorities, hierarchies, lifecycles, and revocation done right (CRL, OCSP, and stapling)
- Windows AD CS end to end: two-tier deployments, templates, autoenrollment, and hardening against ESC1-ESC8 attacks
- Linux CAs with OpenSSL and step-ca, ACME automation, and trust stores for real services
- macOS Keychain and mobile certificate delivery with Intune (SCEP/NDES and PKCS)
- TLS and mutual TLS, S/MIME, code signing, and 802.1X / EAP-TLS network authentication
- Key management, HSMs, and secure key ceremonies
- Cross-platform troubleshooting playbooks that turn "it is broken" into a root cause in minutes
- Post-quantum cryptography and building crypto-agility before you need it
Written for system administrators, security engineers, and IT architects, this guide is organized so you can read it cover to cover or jump straight to the platform and task in front of you. Clear explanations, professional diagrams, runnable commands, and per-chapter checklists make it as useful on the job as it is for study.
