Data Encryption Fundamentals: From Plaintext to Protected
Data encryption and privacy — studied in structured depth, not skimmed over.
Published: 23.04.2026
What this covers
Program Structure
- Week 1: Cipher types, key length, and entropy basics
- Week 2: Symmetric encryption in practice — AES modes, IVs, padding
- Week 3: Asymmetric encryption, RSA, elliptic curve, and TLS handshake mechanics
- Week 4: Key management, storage patterns, and incident case studies
Each week includes one live Q&A session and two structured exercises with feedback.

About this program
Most people enabling HTTPS or ticking a box labeled encrypted storage assume the job is done. It rarely is.
This program looks at encryption as an engineering discipline, not a checkbox. Participants work through how symmetric and asymmetric algorithms behave under different conditions, where key management goes wrong, and what actually happens when a cipher is misused.
Who this is built for
Developers and IT professionals who work with data pipelines, APIs, or user-facing applications. You do not need a cryptography background, but you should be comfortable reading code.
What the sessions cover
The program starts with core concepts: block ciphers, stream ciphers, hashing, and why they are not interchangeable. From there, sessions move into applied scenarios.
Participants examine real incidents where encryption was implemented but still failed. Cases include improper IV reuse, weak key derivation, and misconfigured TLS. Each case is dissected to show the specific mistake and a working fix.
Tools used throughout
OpenSSL, Python cryptography library, and Wireshark for traffic inspection. No proprietary software required.
What you leave with
A working understanding of when and how to apply encryption in your own stack. Also a short reference document covering the most common implementation errors and how to catch them in code review.
Sessions run twice weekly, four weeks total. All recordings available for 90 days after program close.
