  • 0

I am trying to use openSSL to set up an https connection for my application. I’m running a Neo4j 1.2.2 database, with a Trinidad 1.3.5 web server, using the Rails 3.1 and ruby 1.9.

I have a Thawte trial certificate, ca_cert.crt, their intermediate and root certificates, ca_intermediate.crt and ca_root.crt respectively, and my own private key, ca_private.pem. What openssl command do I need to run to create a keystore, which I can specify in my app’s trinidad.yaml config file?

So far the “looks-closest-to-right” thing I’ve tried is:

pkcs12 –export –in ca_cert.crt inkey ca_private.pem –out keystore.p12 –name tomcat

and it gives me the error:

unable to load certificates

error in pkcs12

It looks to me like openssl doesn’t like the format I have the files in, though I have tried nearly every combination of the .pem, .crt, .cer, and .key extensions I can think of to no avail. I’m new to SSL entirely, so I hope I’m just doing something stupid and its an easy fix…

Here is the example I’ve been trying to follow: https://github.com/trinidad/trinidad/wiki/ssl-end-to-end-example

    From this answer it seems that Thawte certificates are formatted as PKCS#7, while openssl pkcs12 -export command expects PEM. Certificate in PKCS#7 can be converted using modified version of command from previously linked answer.

    $ openssl pkcs7 -in ca_cert.crt -print_certs | openssl x509 -outform PEM > ca_cert.pem

    Then executing command, that you provided, creates PKCS#12 keystore.

    $ openssl pkcs12 –export –in ca_cert.pem -inkey ca_private.pem –out keystore.p12 –name tomcat
