The MD5 algorithm was made predictable recently by a security organization.
Upgrade the Gateway with a new SHA-256 algorithm.
This patch is available for all Gateway Appliances and VMWare machines by scanning for updates. The patch information is located below:
"BROKER 2.0-1.16 LDMGA Service daemon 2.0 v.1.16 This updates the security encryption in the connection daemon to replace the older MD5 algorithm with SHA-256"
Note: This update isn't available for the ISO build of the Gateway as it is now end-of-life.
