How can the Key and Salt length be modified in the config.yml file
By default, Key Salt combination for AssistEdge Setup is pulled from the Database. This can be extended to a Json file or custom JS file.
As per default security configurations, the permitted key length validation is set to allow minimum 32 and maximum of 128 characters. Similarly, for Salt, the values are 16 and 32 respectively.
For doing any customization you can refer to Customize Cryptography in Knowledge Base
