Learning objectives

  • Master advanced OpenSSL commands for professional certificate management
  • Develop secure enterprise automation scripts using OpenSSL
  • Implement optimized TLS configurations for high availability
  • Design robust internal PKIs using certifying OpenSSL
  • Optimize key and CSR generation for GDPR compliance
  • Diagnose and resolve OpenSSL vulnerabilities in production
  • Deploy wildcard and EV certificates for critical applications

The Learni story

Founded by engineers and learning experts, Learni's mission is to make high-impact tech training accessible to teams everywhere. We work remotely with organizations across the US and Canada, in your time zone, to help teams upskill fast.

Don't let this gap widen

Why this program matters

  • Without this upskilling, your team accumulates a technological gap that translates directly into productivity loss.

  • Organizations that don't train their talents on key topics see their competitiveness drop.

  • Every quarter without training is a gap widening with competitors who invest.

  • The cost of inaction quickly exceeds that of well-targeted training.

Program

Module 1OpenSSL Certificate Generation and Management: Private Keys, CSRs, and Authorities (CLI, Bash Scripts)

Dive into secure creation of RSA/ECDSA key pairs with OpenSSL, generate X.509 compliant CSRs for submission to external CAs, sign self-signed or intermediate certificates via custom root CAs, validate trust chains with OCSP and CRL, practical exercises on real enterprise scenarios such as Apache web server deployment, produce production-ready deliverables with strong encryption.

Module 2Advanced OpenSSL TLS Configurations: Secure Protocols, Ciphers, and OCSP Stapling

Configure optimal AES-GCM cipher suites and elliptic curves to avoid Heartbleed-like vulnerabilities, implement pure TLS 1.3 with forward secrecy using OpenSSL s_server/s_client, enable HSTS preload and OCSP stapling for maximum performance, test configurations with sslyze and testssl.sh on concrete enterprise cases, develop custom bundles, analyze logs for fine-tuning, obtain tested and immediately deployable certificates.

Module 3OpenSSL Automation and Troubleshooting: Scalable PKIs, Revocations, and Audits (Ansible, Docker)

Automate entire PKIs with OpenSSL scripts integrated into Ansible for mass provisioning in enterprises, manage CRL/OCSP revocations and scheduled key rotations, diagnose memory leaks and weaknesses via fuzzing and valgrind, integrate OpenSSL into Docker containers for secure microservices, resolve real incidents like downgrade attacks, produce complete audits with reports, deploy scalable and certifying end-to-end solution for your infrastructure.

Evaluation method

  • Technical MCQ on OpenSSL commands and TLS protocols
  • Practical evaluation through automation scripts and audits
  • Defense of end-to-end PKI project with vulnerability diagnostics

Learning method

  • Sessions led by operational OpenSSL experts
  • Hands-on exercises on simulated enterprise Linux environments
  • Progressive 3-day PKI thread project
  • Detailed pedagogical support and advanced OpenSSL resources

Methods, materials and delivery

The Training OpenSSL - Securing Certificates and TLS Communications program is delivered onsite or remote (blended-learning, virtual classroom, remote presence). At Learni, an industry-certified training organization, every program is built to maximize skills acquisition regardless of the chosen format.

The trainer alternates between demonstrative, interrogative and active methods (through hands-on labs and/or scenarios). This pedagogical approach guarantees concrete learning that's immediately applicable at work.

Equipment required

For the smooth delivery of the Training OpenSSL - Securing Certificates and TLS Communications program, the following equipment is required:

  • Mac or PC computers, high-speed fiber internet, whiteboard or flipchart, projector or interactive touch screen (for remote sessions)
  • Training environments installed on workstations or accessible online
  • Course materials, hands-on exercises and complementary resources
  • Post-training access to materials and educational resources

For intra-company training on a site outside Learni, the client commits to providing all required teaching materials (computers, internet, etc.) for the smooth delivery of the program in line with the prerequisites in the communicated program.

Skills assessment methods

Assessment of skills acquired during the Training OpenSSL - Securing Certificates and TLS Communications program is performed through:

  • During training: case studies, hands-on labs and professional scenarios
  • End of training: self-assessment questionnaire and skills evaluation by the trainer
  • After training: completion certificate detailing acquired skills

Program accessibility

Learni is committed to making its programs accessible. All our programs are accessible to people with disabilities. Our teams are available to adapt the pedagogical methods to your specific needs. Please contact us for any adjustment request.

Enrollment terms and lead times

Registration is possible up to 48 business hours before the start of training. All our programs are built for corporate L&D budgets and delivered onsite or remotely.

Our method

Training quality, guaranteed at every step

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.
