Answer 1

unzip -p Name-of-apk.apk META-INF/CERT.RSA | keytool -printcert

is what I used.

It produces information such as the owner, issuer, serial number, valid through, certificate finger prints, signature algorithms and version.

I have got the information . Now how to get it as key store – Whitherward

You cannot. The whole point of a keystore is to prevent people who haven't got it to pretend they are you. Unfortunately you probably need to make a new keystore and lose the possibility to smoothly update the app. – Tenuto

This is very useful to find keystore information. Thank you – Vet
