In this video, we demo #Hashicorp #Vault #PKI Secrets Engine for Certificate Management.

Certificate Management is not an easy task. Most Sysadmins dread the day they have to work on renewing a certificate. This is because of a few reasons:

It's a manual and complex process done every few years, so it's hard to remember everything. Most Sysadmins have a Method of Procedure stored somewhere for when they need to go through this process.
It's risky because it incurs an outage during the process.

HashiCorp Vault's Public Key Infrastructure (PKI) secrets engine can streamline distributing TLS certificates and allows users to create PKI certificates with a single command. Vault PKI reduces overhead around the usual manual process of generating a private key and CSR, submitting to a CA, and waiting for a verification and signing process to complete, while additionally providing an authentication and authorization mechanism to validate as well.

It's quite simple to issue certificates with Vault and I'll show you how in this demo video. You can now create shortlived certificates. This is the best practice from a security point of view.

Here we used the Vault Terraform provider to build everything.

Bonus:
I walk you through adding the root and intermediate CA certificates to the Windows 10 Certificate Store. There are also a couple of certutil commands to let you clear the CRL cache so you can see that the certificate is revoked.

In this video demo we go through the following steps:
