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.
