Windows Vista: C:\Users\\.android\debug.keystore

Windows XP: C:\Documents and Settings\\.android\debug.keystore

OS X and Linux: ~/.android/debug.keystore
Open console/terminal on to the above location where debug.keystore file is present and execute

“keytool -list -keystore debug.keystore”

Output will be like (press simply enter when password is asked)

Certificate fingerprint (MD5) will be like this: 00:XX:XX:XX:XX:XX:XX:XX:XX:XX

Step 2
First, unzip the APK and extract the file /META-INF/ANDROID_.RSA (this file may also be CERT.RSA, but there should only be one .RSA file).

Then issue this command:

keytool -printcert -file “\.RSA”
You will get certificate fingerprints like this:

MD5: xx.xx.xx SHA1: xx.xx

Signature algorithm name:

Match Fingerprints and ensure that from which keystore your apk was signed.
