Generate my own key to authenticate fingerprint android

Question

I am creating my first android app (for beginners) and I want users to login using fingerprint

Apparently android stores the fingerprint secretly and I cant access the hashed version.

Is there anyway to create a fingerprint algorithm to be able to get a hashed key from each fingerprint in my app ? I want to see the fingerprint and hash it myself

I hope i was clear in my question :(
