Creating a .jks from a .crt and .key file, is that possible

I requested a SSL certificate from an authority.

First, I created a .csr and a .key file on my computer and saved those. I sent the .csr and got back a .crt file and other files that I installed on my server.

All works fine for my Apache server with an SSL connection. However, I would like to be able to use the same certificate for a Tomcat server that I also have running on the system on a different port (Using JIRA). The setup needs a .jks file. Is it possible to generate that from the files that I have?

This seems like it might work, but I don't have that utility in my CLASSPATH or cannot find it.

  • You can convert a PFX from those files:

    openssl pkcs12 -export -out domain.name.pfx -inkey domain.name.key -in domain.name.crt

    Then export the jks from the PFX by following this guide:
