Setup SSL - Install Certificate help

Ignition
1

Hello,

I am trying to setup SSL (https) on the ignition gateway server, following these instructions: Secure Communication (SSL / TLS) - Ignition User Manual 8.1 - Ignition Documentation

The file I received from "Issuer: Let's Encrypt" contains:

Certificate: (CRT)
-----BEGIN CERTIFICATE-----
content....
-----END CERTIFICATE-----

Private Key (KEY)
-----BEGIN RSA PRIVATE KEY-----
content....
-----END RSA PRIVATE KEY-----

Certificate Authority Bundle: (CABUNDLE)
-----BEGIN CERTIFICATE-----
content....
-----END CERTIFICATE-----

The setup on ignition gateway requires following:

- Private Key
- Certificate Signed By A Certificate Authority (CA)
- Any Intermediate CA Certificates (Provided by your CA)
- Root CA Certificate (Provided by your CA)

What is the mapping here? thanks

A CA Bundle isn't just one certificate. Take a closer look. It will be a chain of multiple certs, including the final Certificate Authority. Split it up.

I took another look.

Certificate Authority Bundle: (CABUNDLE)
-----BEGIN CERTIFICATE-----
content....
-----END CERTIFICATE-----

Content inside looks like a single string to me. How do I split it up?

I would use OpenSSL command line tools. (I always have to open the man pages when I use them, sorry.)
