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.

Fixed In Version: openssl-3.0.0-0.beta2.2.el9
Doc Type: Enhancement
Doc Text:
.`openssl-spkac` can now create SPKAC files signed with SHA-1 and SHA-256 The `openssl-spkac` utility can now create Netscape signed public key and challenge (SPKAC) files signed with hashes different than MD5. You can now create and verify also SPKAC files signed with SHA-1 and SHA-256 hashes.

Description Hubert Kario 2021-06-10 12:04:09 UTC 
Description of problem:
When OpenSSL is asked to create a SPKAC response it signs it with MD5. There are no options available to change that default.

Version-Release number of selected component (if applicable):
openssl-3.0.0-0.alpha16.3.ssl3.x86_64

How reproducible:
always

Steps to Reproduce:
1. openssl genpkey -algorithm RSA -out key.pem
2. openssl spkac -key key.pem -out spkac.pem
3. openssl spkac -in spkac.pem

Actual results:

Netscape SPKI:
