If you are a Windows admin and don’t have openSSL make sure to install it now, your certificate might not be in .pem and you will need that specific format

Steps:

1. Rename your .pem and .key files to user.http.pem and user.http.key
2. Copy the files to /opt/vmware/vcloud-director/data/transfer/ folder (I use Winscp).
3. SSH into the appliance
4. Change the owner and the group permissions on the certificate files to vcloud
   chown vcloud.vcloud /opt/vmware/vcloud-director/data/transfer/user.http.pem
   chown vcloud.vcloud /opt/vmware/vcloud-director/data/transfer/user.http.key
5. Verify that the owner of the certificate files has read and write permissions.
   chmod 0750 /opt/vmware/vcloud-director/data/transfer/user.http.pem
   chmod 0750 /opt/vmware/vcloud-director/data/transfer/user.http.key
6. Run the command below
   /opt/vmware/vcloud-director/bin/cell-management-tool certificates -j –cert /opt/vmware/vcloud-director/data/transfer/user.http.pem –key /opt/vmware/vcloud-director/data/transfer/user.http.key –key-password root-password
7. /opt/vmware/vcloud-director/bin/cell-management-tool cell -i $(service vmware-vcd pid cell) -s
8. wait for at least a minute then execute the command below
   systemctl start vmware-vcd
