Getting Key hash form keystore

Here is the programmatic solution to get Keyhash from keystore.

private void getHashKey() {
try {
  PackageInfo info = getPackageManager().getPackageInfo(getPackageName(), PackageManager.GET_SIGNATURES);

  for (Signature signature : info.signatures) {
MessageDigest md = MessageDigest.getInstance("SHA");
md.update(signature.toByteArray());
Log.e("KeyHash:", Base64.encodeToString(md.digest(), Base64.DEFAULT));
}

} catch (NameNotFoundException e) {
Log.e("name not found", e.toString());
} catch (NoSuchAlgorithmException e) {
Log.e("no such an algorithm", e.toString());
}
}
