I need to provide a string in a helm template that is then sha256 encrypted and dumped out as a hexdigest, then pushed into a json structure.

Currently I have a values file like

Users: - userid: Santa passwd: Claus

and I'm defining a secret like

users.json: {{ .Values.Users | toJson | b64enc }}

but I want the passwd field encrypted as expected by the application. I'm not aware of any helper in helm that provides sha256 encryption so I'm wondering if I can supply my own, and then what the syntax would look like.

Help appreciated.

Thanks.
