Followed Broadcom KB to configure SNMPv3 on vCenter, but it was stuck on generating an authentication hash and privacy hash: How to configure SNMPv3 on the vCenter

During the generation of the authentication and privacy hash, the target files must include the correct password. It does not support an empty password.

To resolve this issue, follow the steps below: 

1. Access the SNMP server to query the password and privacy password.
2. Paste it into both files.
3. Run the command again. The file name can be any name.
4. After the SNMP test, the output should be "successful = true." This means that the SNMPv3 configuration has been completed.
