Changing the Key Store Password of the UltraVR

To enhance system security, you are advised to periodically change the CA key store password of UltraVR . After changing the key store password of UltraVR, you need to restart the UltraVR to make the configuration take effect. You are advised to change the key store password during off-peak hours.

Prerequisites

A cross-platform remote access tool, such as PuTTY, has been obtained.
If the UltraVR management server runs Linux, the password of user root or DRManager has been obtained.

Context

The UltraVR provides the key store bcm.keystore to which the CA certificate of the device is imported. The key store path is fixed to /opt/UltraVR/Runtime/LegoRuntime/certs, and the default key store password is BCM@DataProtect123.
The password complexity requirements of the key store are as follows:
Contains 8 to 18 characters.
Must contain special characters, including ~!@#$%*-_=+[{}];:\,./?
