Are you a DevOps looking to dive into the world of SSL certificates, PKCS, and truststores? This step-by-step guide will show you how to generate SSL certificates using OpenSSL, self-sign them, and then create a truststore using Keytool. Whether you're working on a development environment or preparing your certs for production, this video will cover it all. 💻🔒 In this video, I’ll walk you through: Setting Up Your Certificate Environment: Create your certs folder with mkdir /opt/certs and navigate into it. Generating a CSR (Certificate Signing Request): Learn how to generate a CSR using OpenSSL and create RSA keys for your app. Self-Signing Your CSR: I'll show you how to self-sign the CSR to create an certificate valid for 2 years. Cert Signing with OpenSSL: We’ll cover the process of cert signing using the correct SAN configuration file. Importing Certificates into a Truststore: Once your cert is ready, we'll import it into a Java keystore (JKS) using keytool. Exporting to PKCS#12 Format: I’ll also show you how to export your certificate into PKCS#12 format for easier use in various systems. Step-by-Step Commands Included: openssl req -out -newkey rsa:4096 -keyout -config openssl x509 -req -in -signkey -days 730 -out keytool -import -alias app-name-cert -file -keystore And more... This tutorial is perfect for developers setting up SSL certs for local testing, or anyone needing to manage certificates for their application. 👨‍💻🔐 Timestamp Breakdown: 0:00 - Introduction to SSL Certificates 1:10 - Setting up your certificate folder 2:00 - Generating a CSR with OpenSSL 4:20 - Self-signing your CSR 6:00 - Creating a truststore with Keytool 8:30 - Exporting to PKCS#12 format 10:00 - Conclusion and best practices Don't forget to like, subscribe, and hit the notification bell 🔔 for more tutorials! #SSLCertificates #OpenSSL #Keytool #PKCS12 #JavaKeystore #Truststore #DevOps #DevSecOps #CyberSecurity #Encryption #TLS #HTTPS #CertificateAuthority #SelfSignedCertificate #PublicKeyInfrastructure #PKI #SSLConfiguration #JavaSecurity #LinuxTutorial #ServerSecurity #OpenSSLTutorial #CertificateManagement #CloudSecurity #DevOpsTools #NetworkSecurity #ITSecurity #BackendSecurity #DockerSecurity #KubernetesSecurity #SSLSetup #TechTutorial #LearnDevOps #SysAdmin
