the course
Go beyond HTTPS basics and understand how trust and encryption are implemented in modern IT systems.
Trust is designed. Not assumed.
This SSL Certificates training gives you a practical understanding of TLS, PKI and digital certificates in real-world environments.
From TLS handshakes and X.509 certificates to certificate chains and mutual TLS, you will learn how trust is established — and how it can fail.
You will explore real-world risks, certificate management challenges and automation in DevOps and Kubernetes environments. Learn how to use certificates as a foundation for secure and scalable architectures.
Certificates are the foundation of digital trust.
For IT professionals who work with applications, infrastructure or cloud platforms and want to understand how encryption and certificates really work.
This training is especially relevant if you:
• work as a DevOps engineer, cloud engineer or system administrator
• are responsible for HTTPS, certificates or secure communication
• design or manage APIs, platforms or infrastructure
• want to understand how trust and encryption are implemented in modern IT environments
• want to move from basic knowledge to a practical, end-to-end understanding
This SSL Certificates training is available as a 1-day classroom training (on-site or virtual via Teams/Zoom) and as a self-paced e-learning.
The e-learning consists of 30+ short videos with a total duration of approximately 2–3 hours.
Basic understanding of IT and networking concepts is recommended.
No prior knowledge of encryption, TLS or certificates is required.
If you are new to IT or want to build a broader foundation first, we recommend starting with the IT Fundamentals Training.
This training is suitable for professionals who work with applications, infrastructure or cloud environments and want to understand how HTTPS, encryption and certificates work in practice.
Trust by Design
Course Agenda
Understand the basics of encryption, including symmetric and asymmetric encryption, keys, algorithms and how data is transformed from cleartext to ciphertext.
Learn how HTTPS works and how SSL/TLS secures communication on the internet, including confidentiality, integrity and authentication.
Step-by-step explanation of how a secure connection is established between client and server, including key exchange and session encryption.
Understand what digital certificates are, how they work and how Public Key Infrastructure (PKI) establishes trust between systems.
Learn how certificate authorities (CA), root certificates and intermediate certificates work together to create a chain of trust.
Understand how certificates are validated using CRL and OCSP, and what happens when certificates are compromised or revoked.
Explore one-way and mutual TLS (mTLS) and how certificates are used for strong authentication between systems, users and devices.
Learn how certificates are issued, stored and managed, including keystores, truststores and common certificate formats.
Understand common risks such as self-signed certificates, key management issues and real-world incidents like DigiNotar.
Learn how automation, DevOps and Infrastructure as Code (IaC) are used to manage certificates at scale in modern environments.
Understand how certificates and encryption support Zero Trust architectures and secure communication across modern IT environments.
Explore best practices for certificate management, compliance requirements and future topics such as post-quantum encryption.
Available through preferred suppliers and procurement channels.
