Is there a way to do this in a client-side template?

The sha256Sync API is not available client-side, and I tried using the sha256 API, but I couldn't get that to return the hashed input. Is there a way to do this in a client-side template?

I dont think you can use sha256 API on GTM. My approach is to do hash in my project code then add to data layer
