Creating a .pem with the Entire SSL Certificate Trust Chain. This encodes the key file using an passphrase based on AES256. Concatenate the server certificate, the intermediate certificate, and root certificate. With the openssl ca command we issue a root CA certificate based on the CSR. If the certificate is a part of a chain with a root CA and 1 or more intermediate CAs, this command can be used to add the complete chain in the PKCS12: Note: it is OK to create a password protected key for the CA. Open that file in text editor and stack all 3 certificates on after the other and save. Remember this password. You can create a self-signed certificate using Certificate Assistant in Keychain Access. This will also be the last one we create for this chain. The certificates must be concatenated in order so that each directly certifies the one preceding. The end user certificate was signed using one of the intermediates, which was signed using one of the roots.

Breaking down the command: openssl - the command for executing OpenSSL. P7B files cannot be used to directly create a PFX file. The Root CA is the top level of certificate chain while intermediate CAs or Sub CAs are Certificate Authorities that issue off an intermediate root. You can also generate certificate chains pretty easily with KeyStore Explorer: Create a new key pair, which implies creating a self-signed certificate (the root CA).
