Introduction to PKI and Cryptography Basics
What is PKI?
Definition of PKI and its role
in modern security.
Overview of public and private
keys and their functions in cryptography.
Types of encryption: Symmetric
vs. asymmetric encryption.
PKI Components and Architecture:
Key components of a PKI
system: Certificate Authorities (CAs), Registration Authorities (RAs), digital
certificates, and public/private keys.
Role of digital certificates
in PKI.
Public vs. private key
infrastructure.
Introduction to Cryptographic Algorithms:
Common cryptographic
algorithms: RSA, ECC, AES, and SHA.
How cryptographic algorithms
are used to secure communications and data.
Hands-on Exercises
Digital Certificates and Key Management
Digital Certificates and Certificate
Authorities (CA):
Understanding the structure
and contents of a digital certificate.
Role of the CA in issuing and
verifying certificates.
The process of certificate
creation, validation, and revocation.
Digital Signatures and Certificate Validation:
How digital signatures ensure
data integrity and authenticity.
Certificate chain and
certificate revocation lists (CRLs).
Certificate expiration and
renewal.
Key Management Practices:
Importance of secure key
storage and management.
Key lifecycle management:
generation, distribution, storage, revocation, and destruction.
Tools and practices for
securely managing private keys and certificates.

PKI Implementation and Integration
PKI Use Cases and Applications:
How PKI is used in email
encryption, SSL/TLS, VPNs, and document signing.
Benefits of implementing PKI
in enterprise environments.
Integrating PKI with Applications:
Integrating PKI into web
applications: Securing websites with SSL/TLS certificates.
PKI for VPNs and secure email
(S/MIME).
Using PKI in two-factor
authentication (2FA).
Managing and Troubleshooting PKI Systems:
Monitoring PKI health and
performance.
Troubleshooting common PKI
issues: certificate errors, expired certificates, and revocation failures.
