For example, thepart of thiscommandthatcontains the sensitive information, can be defined as $$value$$ at the property key with regular expression.

***Property key definition***:

nsso.cli.secret\_masking\_pattern= sshpass -v -p "$$value$$" ssh .\*

***CLI Input:***

sshpass -v -p "Password1" ssh [JohnDoe@192.168.1.1](mailto\:JohnDoe@192.168.1.1Session)

***Session and Command Log lines at Single Connect:***

sshpass -v -p "\*\*\*\*\*" ssh JohnDoe\@192.168.1.1
