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.

Description Matthew Harmsen 2017-05-05 16:04:13 UTC 
This bug is created as a clone of upstream ticket:
https://pagure.io/dogtagpki/issue/2680

This was originally found with barbican, though you do not need barbican to see this issue.
You can reproduce using easily using pki.

pki -h localhost -p 18443 -P https -d ~/alee_certdb/ -c redhat123 -n "PKI Administrator for abc.idm.lab.eng.brq.redhat.com" key-generate "my_symkey1" --key-algorithm AES --key-size 256 --usages encrypt,decrypt

root@vm-107 ~]# pki -h localhost -p 18443 -P https -d ~/alee_certdb/ -c redhat123 -n "PKI Administrator for abc.idm.lab.eng.brq.redhat.com" key-retrieve --keyID 0x10
 
PKIException: Recovery Failed recoverSymKey() org.mozilla.jss.crypto.TokenException: Failed to unwrap key

This generation succeeds, but the retrieval fails.  All this succeeds without HSM.
The exception is coming from the HSM when it fails to unwrap the key.

    Fix symmetic key retrieval in HSM
    
    When using an HSM, AES KeyWrapping is not available and so
    some different code paths were exercised.  Fixing bugs in those
    paths uncovered a case where we were calling unwrapSymmetric()
    with bits and not bytes for the key length.
    
    This does not matter for 3DES, where JSS expects a length of 0,
    but very much matters for AES.  Fixing this - and the KeyClient
    to actually use the returned wrapping algorithm to unwrap, allows
    us now to return generated symmetric keys correctly.
