I am fairly new to this but I've done some internet research the last 2 days and I couldn't find an suitable answer.

I have been given a ca-certificate chain (cacertchain.crt) which I need to import to a server running RHEL7 (no GUI). The server has the ca-bundle.crt file. I have tried to put cacertchain.crt to /etc/pki/ca-trust/source/anchors/ and run update-ca-trust and update-ca-trust extract but I couldn't see any changes to the ca-bundle.crt file.

So my question: is there a way of importing a ca-certificate chain (.crt) to RHEL7 keystore?

The certificate chain (cacertchain.crt) includes:

Root Certificate Subject CN - VeriSign Class 3 Public Primary Certification Authority - G5 (I believe this is already available in ca-bundle.crt)

Intermediate Certificate Subject CN - Symantec Class 3 EV SSL CA - G3

  • Import it where? – Michael Hampton Dec 1 '15 at 12:58
  • I just want to add/import it to the server's trusted keystore. As far as I understand for RHEL7 would be the ca-bundle.crt file. I could be wrong though. – daelas Dec 1 '15 at 13:06

    For what purpose? There is no global keystore on Linux operating systems. – Michael Hampton Dec 1 '15 at 13:37
  • In addition to Michael's comment, some of the default applications Red Hat ships do use a central location, as documented in RHEL solution 1549003, but many more do not and will need an application specific configuration... – HBruijn Dec 1 '15 at 14:54
  • Thanks for pointing it out, I though ca-bundle.crt was used as a global keystore. The certs are required by an httpd application (for external connections). – daelas Dec 1 '15 at 14:59

I appears by including the ca-cert bundle in /etc/pki/ca-trust/source/ and running update-ca-trust extract worked fine.

Copy the certificates to /etc/pki/ca-trust/source/anchors/ and after that execute update-ca-trust extract.

They should be available to all application that check that path for certificates (for example wget and curl).

3 steps works for me on this cases:

  1. certificate to /etc/pki/ca-trust/source/anchors/
  2. update-ca-trust force-enable
  3. update-ca-trust extract
