Clear Passwords in YAML files?

I wanted to see if there was any plan to encrypt/hide the various passwords that are now being stored in the YAML configuration files, such as:

pia_gateway_user:      administrator

pia_gateway_user_pwd:  ***

domain_conn_pwd:  ***

db_user:           VP1

db_user_pwd:       ***

db_connect_id:     people

db_connect_pwd:    ***

The concern is that having passwords in clear text on the server could be a security risk.

Thanks,

Sean
