Program

Code Obfuscation curriculum: 4 modules over 4 days

Module 1 : Code Obfuscation Fundamentals: Principles and Basic Tools (JavaScript Obfuscator, UglifyJS)

Dive into obfuscation mechanisms to protect your source code, install and configure JavaScript Obfuscator as well as UglifyJS on real projects, apply basic transformations like variable renaming and minification, test the impact on readability using analysis tools, produce your first obfuscated file with practical exercises and immediate trainer feedback.

Module 2 : Advanced Code Obfuscation Techniques: Control Flow and Encryption (Webpack Obfuscator, ProGuard)

Master control flow and string encryption to harden your code, integrate Webpack Obfuscator into a modern workflow, configure ProGuard for Java with dead code elimination, simulate reverse engineering attacks on your obfuscated scripts, optimize aggressiveness levels through real enterprise cases, generate analysis reports and adjust in real-time for optimal protection.

Module 3 : Multi-Language Code Obfuscation: JavaScript, Java, and Mobile (JScrambler, DexGuard)

Adapt obfuscation to various environments like Node.js JavaScript, Java Android, and mobile apps, deploy JScrambler for advanced runtime protection, explore DexGuard for APKs with string encryption, work on a multi-platform ongoing project, analyze language-specific vulnerabilities through practical audits, produce production-ready secure builds with group validation.

Module 4 : Code Obfuscation Integration and Testing: CI/CD and Evaluation (Jenkins, GitHub Actions)

Integrate automated obfuscation into CI/CD pipelines with Jenkins and GitHub Actions, test robustness against de-obfuscation tools like JSNice, measure post-processing performance and binary sizes, apply to a complete enterprise case with simulated deployment, finalize your certifying ongoing project, receive personalized advice for immediate team implementation.

Our method

How Learni guarantees the quality of your Code Obfuscation training

Before, during, after: we frame the brief, introduce the trainer, tailor the content and measure impact. You stay in control from kickoff to wrap-up.

Step 1

Rigorous trainer selection

Each trainer is validated on three criteria: hands-on field expertise, proven pedagogy and alignment with your industry.

  • Triple validation: technical, pedagogical, sectoral.
  • Minimum rating 4.8/5 over the last 12 sessions.
Step 2

You meet the trainer beforehand

30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.

  • Live briefing on goals and team context.
  • Veto right — we swap the trainer for free if needed.
Step 3

Content tailored to your context

No recycled slides. The syllabus is reworked from your real cases: tools, constraints, vocabulary, ongoing projects.

  • Hands-on cases drawn from your stack and projects.
  • Program co-written then validated by your team.
Step 4

Continuous quality follow-up

Live evaluations, 30/90/180-day check-ins and a consolidation plan. If the impact misses the mark, we rework it.

  • NPS, knowledge quizzes and skills self-assessment.
  • Satisfaction guarantee: fully satisfied or free rework.

A simple promise: you don't pay to discover the trainer on day one. Everything is validated upfront, by you.
