Learn OpenSSL with a real world cheatsheet
Learn how to use OpenSSL tools to generate public and private keys, add/remove encryption, generate certificates and CSRs, and understand different file formats. This course equips you with the skills to inspect and troubleshoot SSL/TLS scenarios. Perfect for those involved in SSL/TLS installation, configuration, and troubleshooting.
What you’ll learn
- How to use OpenSSL tools
- How to generate Public and Private Keys
- How to add & remove Encryption to RSA Keys
- How to generate Certificates and CSRs
- Understand and convert between different File Formats (PEM, DER, PFX)
OpenSSL is the universal tool for inspecting, diagnosing, and troubleshooting SSL & TLS.
OpenSSL is composed of many different utilities, each of which is responsible for a specific aspect of the SSL and TLS ecosystem.
Topics include:
Module 1 – Generating Public and Private Keys
Generating and inspecting RSA Keys
Generating and inspecting DSA Keys
Generating and inspecting Elliptic Curve Keys
Adding & Removing Encryption to RSA Keys
Adding and removing encryption to RSA Keys
OpenSSL Key Utility
Matching Private Keys to Certificates and CSRs
Module 3 – Generating Certificates and CSRs
Creating a CSR and Certificate using an existing Private Key
Creating a CSR and Certificate using a new Private Key
Module 4 – Inspecting Certificates and CSRs
Extracting specific information from Certificates and CSRs
Module 5 – File Formats and Conversions (PEM, DER, PFX)
Check if file is PEM, DER, or PFX
Converting files between PEM and DER formats
Converting files between PEM and PFX formats
In this course, you will receiving training on how to use the following OpenSSL Utilities:
openssl rsa
openssl genrsa
openssl dsa
openssl gendsa
openssl dsaparam
openssl ec
openssl ecparam
openssl pkey
openssl genpkey
openssl x509
openssl req
openssl pkcs12
Each module contains demo files you can use to practice the commands along with each lesson.
The lessons in the course follow a section from the Cheat Sheet (available to download as part of the course).
After completing the course and downloading the OpenSSL Cheat Sheet,
you will be equipped to inspect and troubleshoot any SSL / TLS scenarios you find yourself in.
