Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.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 Nikos Mavrogiannopoulos 2016-09-05 11:35:20 UTC
The CHACHA20-POLY1305 algorithm is specified in rfc7539, and is being adopted by TLS 1.3 and IPSec (rfc7634). It is becoming the de-facto backup algorithm of AES-GCM (implemented in all major browsers), and is being included into all major crypto libraries. 

We should include chacha20-poly1305 in RHEL7 when possible.

Comment 1 Tomas Mraz 2016-09-05 11:45:12 UTC
chacha20-poly1305 is not present in openssl 1.0.2 branch. Rebasing to 1.1.0 is impossible and that means the chacha20-poly1305 support would have to be backported. It would be severally non-trivial and I do not think this is feasible for 7.4. We might consider the backport for future RHEL-7 update if there is strong customer demand.

Comment 4 Tomas Mraz 2017-11-28 16:36:55 UTC
The chachapoly support is not going to be included in openssl-1.0.2
