OpenSSL Tutorial Video-9 | Setting up two-tier CA (Certificate Authority) using OpenSSL

#OpenSSL #PKI In this video, I will teach you how to setup PKI with two-tier CA using OpenSSL. This would include a Root CA and an Issuing CA. First I will explain what PKI (Public Key Infrastructure) is then I will show you how to setup a Root CA and an Issuing CA using OpenSSL. Finally I will demonstrate how to issue a CA signed certificate and revoke them. Please access my notes and configuration files from the link below -- https://github.com/CyberHashira/Learn_OpenSSL/ Direct link to my notes - https://github.com/CyberHashira/Learn_OpenSSL/blob/main/Setup_Two_Tier_PKI_Using_OpenSSL.txt Video Timelines - 0:00 - Intro 0:50 - PKI overview. 1:52 - Different types of CA. 3:49 - Root-CA and Intermediate-CA 5:30 - Certificate Revocation List. 7:05 - Setup files and directories for CA. 13:24 - Configuring Root CA. 20:14 - Generating Keys for Root CA. 23:54 - Configuring Issuing CA. 27:21 - Generating Keys for Issuing CA. 32:42 - Issuing a WebServer certificate. 37:29 - Issuing a Codesigning certificate. 40:57 - Revoking a certificate. 44:35 - Thanks for watching.
