About Kreuo Pwixa

Where encryption becomes a skill, not a concept

Kreuo Pwixa is an online seminar platform focused on data encryption and privacy. Sessions are built for people who want to understand the mechanics behind security — not just the terminology.

What we do

Built around real security problems

Most encryption courses explain protocols. Kreuo Pwixa seminars start from a specific threat, then work backward to the encryption decision. Participants leave with a mental model they can apply, not a list of definitions.

"Understanding AES-256 without knowing when to use it — and when not to — is the most common gap in technical security education."

— Core teaching principle, Kreuo Pwixa curriculum

Typical course
Kreuo Pwixa seminar
Defines symmetric vs. asymmetric encryption
Demonstrates a key-exchange failure and traces it to the algorithm choice
Lists GDPR principles
Maps specific data flows to GDPR Articles 25 and 32 with concrete examples
Covers RSA at a surface level
Examines why 1024-bit RSA was deprecated and what replaced it in TLS 1.3
Q&A at the end of a recorded video
Live discussion with scenario-based peer exercises during each session
The people behind it

Instructors with field experience

Odalys Ferreira, lead encryption instructor

Odalys Ferreira

Lead Encryption Instructor

Odalys spent eight years as a security engineer before moving into education. Her seminars focus on the TLS handshake, certificate chains, and the practical decisions behind key rotation schedules.

Ruzena Blahova, privacy and compliance instructor

Ruzena Blahova

Privacy & Compliance Instructor

Ruzena covers the regulatory side — GDPR, data residency, and encryption at rest requirements for cloud environments. She brings a legal-technical perspective that most engineering courses skip entirely.

Tadeus Wronka

Cryptographic Protocols Instructor

Tadeus leads sessions on hash functions, digital signatures, and post-quantum cryptography. He designs the scenario exercises that run across multi-session seminars, giving participants layered problems to return to.

Kreuo Pwixa by the numbers

Founded in 2024, the platform has maintained a focused curriculum — fewer broad topics, more depth per session. Each number below reflects a deliberate choice in how we run seminars.

6+ Active seminar tracks
3h Average session length with discussion
18max Participants per session — kept small deliberately
4levels From introductory to advanced cryptographic protocol design

Sessions run online. Participants from Ternopil and surrounding areas join without travel dependency — the schedule is fixed, the attendance is flexible within that.
