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.

@PratikButani, hi. Could you figure out how ti use this information to generate a keystore file or sign an .apk file? – Ayaz Alifov Jul 13 '18 at 14:49
I have got the information . Now how to get it as key store – Biswajit Das Nov 13 '19 at 09:59
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. – Mauro Vanetti Feb 16 '23 at 09:09
This is very useful to find keystore information. Thank you – Pratius Dubey May 23 '23 at 08:11
