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: gnutls-3.3.26-1.el7
Doc Type: Enhancement
Doc Text:
Feature: This adds support for decoding private keys encrypted using openssl version 1.1.0. Reason: OpenSSL 1.1.0 changed its default encoding format for PKCS#8 private keys, involving HMAC algorithms not handled in GnuTLS for PKCS#8 private key decoding. Result: This change ensures keys generated using OpenSSL 1.1.0 will be decoded by gnutls applications.

Description Nikos Mavrogiannopoulos 2016-09-30 08:50:27 UTC 
+++ This bug was initially created as a clone of Bug #1369484 +++

GnuTLS (for example openconnect) can read PKCS#8 files generated by Fedora's OpenSSL 1.1.

It started at OpenSSL commit 8fc06e8860:
https://github.com/openssl/openssl/commit/8fc06e8860

Specifically, changing the PRF to use SHA256. So this works:

$ apps/openssl pkcs8 -topk8 -in ~/privkey.pem -out ~/pk8-test.pem -v2 aes256 -passout pass:asdf -v2prf hmacWithSHA1

... and GnuTLS fails to parse this one:

$ apps/openssl pkcs8 -topk8 -in ~/privkey.pem -out ~/pk8-test.pem -v2 aes256 -passout pass:asdf -v2prf hmacWithSHA256
