I recently deployed a Dart server application that serves HTTP requests. I wanted to add support for HTTPS so I have been trying to add SSL to the Dart server application.

This answer gives a clear explanation of how to add a self-signing SSL certificate to Dart. However, I want to add an SSL certificate I bought from an SSL provider.

The SSL provider e-mailed my 4 files:

Root CA Certificate - AddTrustExternalCARoot.crt

Intermediate CA Certificate - COMODORSAAddTrustCA.crt

Intermediate CA Certificate - COMODORSADomainValidationSecureServerCA.crt

Your PositiveSSL Certificate - my_domain.crt

I have been trying to figure out how certutil works and how to add these certificates to the certificate database, but I just can't figure it all out.

Anyone with experience enabling a CA SSL certificate in Dart?

SOLVED: Thanks to suggestion in the comments, I solved the issue. This is the gist of my complete setup: https://gist.github.com/stevenroose/e6abde14258971eae982
