Intermediate CA

Ordering certificate when using intermediates

When using intermediate certificate(s), we need to make sure that:

  • the application using the certificate is sending the complete chain (server certificate and intermediate certificate).

  • and usually we have to create a file containing the server certificate file and the intermediate certificate file.

  • it is required to put the server certificate file first, and then the intermediate certificate file(s).

  • we can create the correct file for the chain using: cat cert.pem intermediate.pem > chain.pem
