How do I find out which keystore was used to sign an app?

Question

I have an app which is signed and several keystore files. I\'d like to update the app, so I need to find out which one of keys was used.

How can I match which keysto

Answer 1

Much easier way to view the signing certificate:

jarsigner.exe -verbose -verify -certs myapk.apk

This will only show the DN, so if you have two certs with the same DN, you might have to compare by fingerprint.
