[FIXED] How to generate hash signature?

Issue

I am using twilio sdk to integrate sms verification with my android app, twilio asks me to register hash signature of my app and non of ways to generate hash signature worked, always says it is invalid hash signature this is the path that twilio wants the hash signature

Solution

User below command in terminal of android studio to generate release key hash

keytool -exportcert -alias [aliasname] -keystore [your app keystore path] | openssl sha1 -binary | openssl base64

And below code in your project to get development key hash

try {
    android.content.pm.PackageInfo info = getPackageManager().getPackageInfo(
            "com.apps.sonictonic",
            android.content.pm.PackageManager.GET_SIGNATURES);
    for (android.content.pm.Signature signature : info.signatures) {
        java.security.MessageDigest md = java.security.MessageDigest.getInstance("SHA");
        md.update(signature.toByteArray());
        android.util.Log.d("KeyHash", "KeyHash:" + android.util.Base64.encodeToString(md.digest(),
                android.util.Base64.DEFAULT));

    }
} catch (android.content.pm.PackageManager.NameNotFoundException e) {

} catch (java.security.NoSuchAlgorithmException e) {

}
