SECURE PROVISIONING
Although the XML config file can be encrypted and the encryption algorithm itself is regarded as safe and
strong by using AES with 256-bit key length, it remains a question on how to bootstrap and provision the
initial XML encryption password. There are several methods to provide solutions to this:
1. Use legacy binary config file to set the initial XML encryption password. The legacy binary file is
encrypted and it generally regarded safe.
2. Use HTTPS and use client side authentication. This is the industry standard approach and has
the strongest safety.
