Troubleshooting a Pure1 Connection with the vSphere Plugin

In the 4.2.0 release of the vSphere Plugin, we added Pure1 integration which provided additional insight into your Pure Storage and vSphere Environment. In order to use this though, you need to connect the plugin with Pure1 of course. The authentication method is based on a process which involves something called a JSON Web Token. This is a secure option, but a bit more involved than a user name and password. I made the process of generating this fairly easy, but if something goes wrong you get a fun error message like below:

Pure1 REST API Authentication Made Easy

I’ve been working with the Pure1 REST for about a year now and have really enjoyed what it brings. I’ve integrated it into a few things: PowerShell. vRO. vSphere Plugin. One of the “tricky” things about it though is the authentication. Instead of a username and password it requires the use of a RSA256 public/private key pair. This is inherently more secure, but of course requires a bit more know-how when it comes to pair generation.

I simplified a fair amount of it in PowerShell, but didn’t quite get to the finish line. The generation of the key pair could be done but it came in the form of a PFX–which basically combines the public key and private key into one file. Unfortunately, Pure1 requires the them to be separated as all it needs is the public key, not your private key. While this is “better” it does leave Windows users at a bit of a disadvantage–there is no built in mechanism to generate this without installing OpenSSL directly. The process could not be done entirely in PowerShell. Or so I thought…
