Doc Text:
Previously, the ssh server in the rhgs-server container image supported sha1 kex algorithms. These are considered weak algorithms and need to be disabled. With this update, the default configuration in the sshd config does not include the sha1 based kex algorithms. For more information, refer to https://access.redhat.com/solutions/4278651.
