This Solution article lists the steps to create a signed certificate using the CSR.
1. Create your private key and the Certificate Signing Request.
openssl req -new -newkey rsa:2048 -nodes -keyout iwx-app.infoworks.cloud.key -out iwx-app.infoworks.cloud.csr
The above OpenSSL command will generate the Certificate Signing Request (CSR) iwx-app.infoworks.cloud.csr and the private key file iwx-app.infoworks.cloud.key.
2. Submit the CSR to a Certification Authority ( CA )
Submit this CSR to a third-party CA like GoDaddy, DigiCert, CaCert, Cloudfare to get the signed certificate.
3. You would get a bundle with the below files if your CA is GoDaddy.
gd_bundle-g2-g1.crt is the intermediate crt
