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 Jiri Jaburek 2014-04-03 14:50:51 UTC 
Description of problem:

on rhel-6, gnutls-2.8.5-13.el6_5 correctly generates nonencrypted key:

$ certtool --generate-privkey --pkcs8 --outfile pkcs8.key
Generating a 2048 bit RSA private key...
Enter password: 
Confirm password: 
$ head -n1 pkcs8.key
-----BEGIN PRIVATE KEY-----
$ openssl pkcs8 -nocrypt -in pkcs8.key
-----BEGIN PRIVATE KEY-----
MIIEvgIBADANBgkqhkiG9w0BAQEFAASCBKgwggSkAgEAAoIBAQDE6WwcTPk3Qpex
<snip>
-----END PRIVATE KEY-----

on rhel-7, gnutls-3.1.18-8.el7 doesn't want confirmation and generates an encrypted key:

$ certtool --generate-privkey --pkcs8 --outfile pkcs8.key
Generating a 2432 bit RSA private key...
Enter password: 
$ head -n1 pkcs8.key
-----BEGIN ENCRYPTED PRIVATE KEY-----
$ openssl pkcs8 -nocrypt -in pkcs8.key
Error decrypting key
140405575759776:error:0906D06C:PEM routines:PEM_read_bio:no start line:pem_lib.c:703:Expecting: PRIVATE KEY


Version-Release number of selected component (if applicable):
gnutls-3.1.18-8.el7

How reproducible:
always

Actual results:
certtool generates encrypted key when empty password is used

Expected results:
certtool generates non-encrypted key when empty password is used


Additional info:

While the --password option doesn't seem to be working on rhel-6 in this case, it works on rhel-7 and can be used as a workaround:

$ certtool --generate-privkey --pkcs8 --password "" --outfile pkcs8.key
Generating a 2432 bit RSA private key...
$ head -n1 pkcs8.key
-----BEGIN PRIVATE KEY-----
$ openssl pkcs8 -nocrypt -in pkcs8.key
-----BEGIN PRIVATE KEY-----
