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the product is no longer active in Red Hat Bugzilla.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.

Description of problem: certtool --to-p12 always uses hmacWithSHA256
Version-Release number of selected component (if applicable): gnutls-3.7.3-1.el9
How reproducible: always
Steps to Reproduce:
1. openssl req -x509 -newkey rsa -keyout localhost.key -out localhost.crt -subj /CN=localhost -nodes -batch
2. certtool --to-p12 --outder --p12-name localhost --load-certificate localhost.crt --load-privkey localhost.key --outfile p12 --password pass --hash SHA512
3. openssl pkcs12 -in p12 -info -nodes -noout -passin pass:pass
Actual results:
MAC: sha512, Iteration 600000
MAC length: 64, salt length: 8
PKCS7 Encrypted data: PBES2, PBKDF2, AES-128-CBC, Iteration 600000, PRF hmacWithSHA256
Certificate bag
PKCS7 Data
Shrouded Keybag: PBES2, PBKDF2, AES-128-CBC, Iteration 600000, PRF hmacWithSHA256
Expected results:
MAC: sha512, Iteration 600000
MAC length: 64, salt length: 8
PKCS7 Encrypted data: PBES2, PBKDF2, AES-128-CBC, Iteration 600000, PRF hmacWithSHA512
Certificate bag
PKCS7 Data
Shrouded Keybag: PBES2, PBKDF2, AES-128-CBC, Iteration 600000, PRF hmacWithSHA512
Additional info:
* maybe the control doesn't have to be --hash
* int gnutls_pkcs12_bag_encrypt(gnutls_pkcs12_bag_t bag, const char * pass, unsigned int /*gnutls_pkcs_encrypt_flags_t*/ flags)
doesn't have a readily available avenue to pass a choice of a PRF, so this might entail quite some work
* code reference: https://gitlab.com/gnutls/gnutls/-/blob/c87f5aa5fd5a807a4444e428063db3f8635d378d/lib/x509/pkcs7-crypt.c#L1579
* related change: bz1764199
* wishlist-grade, as this should be workaroundable
