Setup Firebase Auth in EXPO command line

I’m trying to connect my firebase auth to an expo project. I’m following the main docs of each library. I’m stucking on this step.

I’m not able in windows to exeute this command line openssl rand -base64 32 | openssl sha1 -c . I’ve tried with the specific https://code.google.com/archive/p/openssl-for-windows/downloads but I don’t know how to reproduce the same line.

Any help would be great, thanks in advance.
