Command Line to change DES encrypted password in Alias

[dataprep]

The issue : we have to regurlary change our passwords. It implies changing it for all the connections alias (at least for standard connections). 

What I'm looking for :

A commande line to execute like :
alteryxpw.exe -connection {alias name} -connection_type {user/system} -connection_mode {standard/indb} -pw {new password}

This command line could be executed by a powerhsell script.
