.KEY and .CSR files but no .CRT file

I'm working migrating a Java app to NodeJS, they are using SSL and they gave me some files related with this:

www.domain.com.key
www.domain.com.csr

But I'm not an expert on this topic, and I'm trying to setting up the SSL certificate with Express but it seems a .CRT file is also required.

I asked them, but they told me that .CRT is actually inside of the .CSR file.

Not sure what should I do to make it work, I've been reading and doing lots of things without success, any idea?

Thanks.

Solution

  • The .key file is probably your PRIVATE key

    The .csr file is a CERTIFICATE REQUEST probably signed with your private key

    What you need is probably a .crt : a certificate corresponding to your csr signed by a certificate authority (or self signed, depending what you want to accomplish)

    node (like another web server) is supposed to ask you 3 thing : - your private key - the certificate - the certificate chain, eventually, depending of the certificate

    What you can do is open with a text editor the different files, and see if you see the certificate inside:

    you should see things like -----BEGIN CERTIFICATE----- or -----BEGIN PRIVATE KEY----- or -----BEGIN CERTIFICATE REQUEST----- , that will told you the exact content of the files.
