You can install certificates, signed with the SHA-1 hashing function in case your environment requires it.

By default, the vSphere Replication server rejects installation of new certificates, which are signed with the SHA-1 hashing function. To install a certificate, signed with the SHA-1 hashing function, you must enable it in the vSphere Replication appliance.

Procedure

  1. Establish an SSH connection to the vSphere Replication Appliance.
  2. Navigate to /opt/vmware/hms/conf/.
  3. Open hms-configuration.xml in a text editor and set the <hms-allow-legacy-hash-algo> value to true.
  4. Restart the vSphere Replication service.
