1579384 – [RFE] add check for key usage Key Encipherment to katello-certs-check

Red Hat Satellite engineering is moving the tracking of its product development work on Satellite to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "Satellite project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs will be migrated starting at the end of May. If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "Satellite project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/SAT-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Paul Dudley 2018-05-17 14:02:58 UTC

Currently, using certs without Key Encipherment will pass katello-certs-check, but these certificates will ultimately fail when clients attempt to retrieve updates:

From a client update attempt:
https://satellite.example.com/pulp/repos/ORG/ENV/VIEW/content/dist/rhel/server/7/7Server/x86_64/optional/os/repodata/repomd.xml: [Errno 14] curl#60 - "Certificate key usage inadequate for attempted operation."

Certificates without Key Encipherment should fail in the certs check to avoid deployment of certs that ultimately fail when used.

VERIFIED

Version tested:
Satellite 6.4 snap 17

#  openssl x509 -text -in server.valid.crt -noout | grep -A1 "Key Usage"
            X509v3 Key Usage: 
                Digital Signature, Non Repudiation, Key Encipherment, Data Encipherment


Checking server certificate's encoding: [OK]
Checking expiration of certificate: [OK]
Checking expiration of CA bundle: [OK]
Checking if server cert has CA:TRUE flag[OK]
Validating the certificate subject= /C=IN/ST=Maharashtra/L=Pune/O=redhat/OU=QE/CN=xyz/emailAddress=administrator
Checking to see if the private key matches the certificate: [OK]
Checking ca bundle against the cert file: [OK]
Checking Subject Alt Name on certificate[OK]
Checking Key Usage extension on certificate for Key Encipherment[OK]

Validation succeeded.

To install the Katello main server with the custom certificates, run:

    satellite-installer --scenario satellite\
                      --certs-server-cert "/root/server.valid.crt"\
                      --certs-server-key "/root/server.key"\
                      --certs-server-ca-cert "/root/rootCA.pem"

To update the certificates on a currently running Katello installation, run:

    satellite-installer --scenario satellite\
                      --certs-server-cert "/root/server.valid.crt"\
                      --certs-server-key "/root/server.key"\
                      --certs-server-ca-cert "/root/rootCA.pem"\
                      --certs-update-server --certs-update-server-ca

To use them inside a NEW $FOREMAN_PROXY, run this command:

    capsule-certs-generate --foreman-proxy-fqdn "$FOREMAN_PROXY"\
                                 --certs-tar  "~/$FOREMAN_PROXY-certs.tar"\
                                 --server-cert "/root/server.valid.crt"\
                                 --server-key "/root/server.key"\
                                 --server-ca-cert "/root/rootCA.pem"\

To use them inside an EXISTING $FOREMAN_PROXY, run this command INSTEAD:

    capsule-certs-generate --foreman-proxy-fqdn "$FOREMAN_PROXY"\
                                 --certs-tar  "~/$FOREMAN_PROXY-certs.tar"\
                                 --server-cert "/root/server.valid.crt"\
                                 --server-key "/root/server.key"\
                                 --server-ca-cert "/root/rootCA.pem"\
                                 --certs-update-server
