I am currently able to create the Root and A certificates via the below, but I haven't found how to make a longer chain: # Root certificate is created like this: openssl req -new -newkey rsa:1024 -nodes -out ca.csr -keyout ca.key openssl x509 -trustout -signkey ca.key -days 365 -req -in ca.csr -out ca.pem # Certificate A is created like this

ECA Certificate Chain Manual Installation. Before you can use your IdenTrust ECA digital Certificates, the IdenTrust ECA Subordinate and ECA Root Certificate must be installed in your browser. This process is performed automatically during the retrieval of the certificate. Steps to install only the IdenTrust Subordinate CA Certificate A certificate chain contains one or more certificates. You can use a text editor, the copy command in Windows, or the Linux cat command to concatenate your certificate files into a chain. The certificates must be concatenated in order so that each directly certifies the one preceding. The way Windows displays certificate details is very succinct. Specifically, the certificate chain. See screenshot as an example. And here it is again in Windows, but using the certutil tool. (okay it's inspecting a pfx but you get the point).

The paragraph discusses the fact that servers do not always return the entire certificate chain during an SSL handshake, hey often return only the server certificate and the root CA of the chain. The chain are showed using openssl like: openssl s_client -connect egov.uscis.gov:443. This gave me some doubts:

I have a PKCS12 file containing the full certificate chain and private key. I need to break it up into 3 files for an application. The 3 files I need are as follows (in PEM format): an unecrypted key file; a client certificate file; a CA certificate file (root and all intermediate)

Certificate chain (or Chain of Trust) is made up of a list of certificates that start from a server’s certificate and terminate with the root certificate. If your server’s certificate is to be trusted, its signature has to be traceable back to its root CA.

All of our intermediate certificates and certificate bundles are also available from the repository. Note: If you don't install the intermediate certificates with your issued SSL certificate, the trusted-chain certificate might not be established.
