2041832 – openssl pkcs12 unable to process nss pk12util generated pkcs12 file if its password length is >= 64 chars

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 Anton Bobrov 2022-01-18 10:59:49 UTC

Description of problem:

It is not clear to me whether this is openssl pkcs12 or nss pk12util problem so please feel free to re-assign as appropriate.

When exporting with pk12util if one specifies a password password length is >= 64 chars the export succeeds however openssl pkcs12 fails to process resulting pkcs12 file.

Version-Release number of selected component (if applicable):

How reproducible:

This is easy to reproduce even with the latest versions eg on the latest Fedora.

Steps to Reproduce:

### USING A 64 BYTES (OR LONGER) p12filePassword ###
pk12util -o ./test.p12 -d ./ -k ./pwdfile.txt -n Server-Cert -W 1234567890123456789012345678901234567890123456789012345678901234
# pk12util: PKCS12 EXPORT SUCCESSFUL

openssl pkcs12 -in ./test.p12 -out ./test.cert -clcerts -nodes -passin pass:1234567890123456789012345678901234567890123456789012345678901234
