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the product is no longer active in Red Hat Bugzilla.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.
+++ This bug was initially created as a clone of Bug #608639 +++
Description of problem:
The various sub-commands of openssl that use digests only list a few older types and do not indicate there are more available.
How reproducible:
$ openssl x509 -h
[snip]
-md2/-md5/-sha1/-mdc2 - digest to use
$ openssl req -h
[snip]
-[digest] Digest to sign with (md5, sha1, md2, mdc2, md4)
$ man x509
[snip]
-md2|-md5|-sha1|-mdc2
the digest to use.
etc.
And the dgst sub-command man page does not provide the full list of supported digests.
Only by calling the dgst sub-command with an invalid parameter can one see the full list of digests available.
-md5 to use the md5 message digest algorithm (default)
-md4 to use the md4 message digest algorithm
-md2 to use the md2 message digest algorithm
-sha1 to use the sha1 message digest algorithm
-sha to use the sha message digest algorithm
-sha224 to use the sha224 message digest algorithm
-sha256 to use the sha256 message digest algorithm
-sha384 to use the sha384 message digest algorithm
-sha512 to use the sha512 message digest algorithm
-mdc2 to use the mdc2 message digest algorithm
-ripemd160 to use the ripemd160 message digest algorithm
Additional info:
Since the list can change probably the best solution would be to have the various sub-commands indicate there are more digests available, and give the dgst a clearer method of listing the full list of those available.
Since the problem described in this bug report should be
resolved in a recent advisory, it has been closed with a
