Note: This bug is displayed in read-only format because
the product is no longer active in Red Hat Bugzilla.
RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 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 "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". 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 "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-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.
.`redhat-support-tool` does not work with the `FUTURE` crypto policy
Because a cryptographic key used by a certificate on the Customer Portal API does not meet the requirements by the `FUTURE` system-wide cryptographic policy, the `redhat-support-tool` utility does not work with this policy level at the moment.
To work around this problem, use the `DEFAULT` crypto policy while connecting to the Customer Portal API.
Hello all,
one of our customers just reported the following issue on RHEL 8.1.
Current behavior:
Setting the system crypto-policy to FUTURE is blocking the communication of redhat-support-tool with Customer Portal API.

Problem connecting to the support services API. Is the service accessible from this host?

When we use some other crypto policy, the communication is working fine. The FUTURE crypto policy is very strict and probably is disabling cipher-suite needed for the communication:
https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html/security_hardening/using-the-system-wide-cryptographic-policies_security-hardening
Expected behavior:
redhat-support-tool should work with the FUTURE crypto policy set.
The FUTURE policy has a special purpose and is not meant to be used in general. It will not be adjusted because it would hinder its purpose.
If the redhat-support-tool has to work with the FUTURE policy set it needs to be solved (on the server side) of the redhat-support-tool.
Hello Tomas,
yes, that's fine. We do not expect to change the setting of crypto policies.
Can somebody from PM review this request and let us know if support-tool should work with this settings (IMHO it should).
Many thanks,
-Roman
Basically it means that the servers that the support-tool connects to have to have 3kbit RSA certificates (or ECDSA certificates) as minimum.
(There might be other issues but they are much less probable.)
@vikas
The certificate that is directly on the Strata pods in production is for strata.ext.us-west.dc.prod.paas.redhat.com. That certificate was renewed in June, 2019 and is 4096 bits. However, the curl that @roman face showed the following certificate was flagged:
* Server certificate:
* subject: C=US; ST=North Carolina; L=Raleigh; O=Red Hat, Inc.; OU=Engineering; CN=maven.repository.redhat.com
* start date: Jan 13 00:00:00 2020 GMT
* expire date: Jul 14 12:00:00 2020 GMT
* issuer: C=US; O=DigiCert Inc; OU=www.digicert.com; CN=GeoTrust RSA CA 2018
* SSL certificate verify result: EE certificate key too weak (66), continuing anyway.
This certificate is for the maven server that both Strata and Hydra connect to. I can't renew it since Strata doesn't own the maven server. However, the certificate expires in July so it will need to be renewed soon and the updated certificate should be 4096 bits.
