Fetching the certificate fingerprint if an apk is signed with only v2 Signing Scheme

Question

The v2 signing scheme works (referred in the link) v2 Signing Scheme I have few doubts regarding the same.

If an apk is only signed with v2 signing scheme (not by v1 signing scheme) then, how to fetch the certificate fingerprint of an apk? The problem is there is no (CERT.RSA) file over there.

I tried searching a lot over the internet but everywhere solution is given w.r.t when v1 signing scheme is used. Which existing tool can be used to extract APK Signing block?

Answer 1

Apksigner is the tool to use:

apksigner verify --print-certs -verbose app.apk

apksigner is shipped with the Android SDK Build Tools.
