How to configure GuacamoleClient Authorization encoding to use SHA256 for GuacamoleExt plugin

[Amartya Thorat]

Hi Team
I am using GuacamoleExt for Authentication by extending
SimpleAuthenticationProvider
override the method getAuthorizedConfigurations
So my question is how we can configure/set client Authorization.java
encoding to use SHA256
I tried following to set encoding

GuacamoleConfiguration config = new GuacamoleConfiguration();
config.setParameter("encoding","sha256"s);

Is that correct?

Thank you once again

Thanks,
Amartya
