Could not generate secret key #61

Closed PXNX closed 3 years ago

PXNX commented 3 years ago

I'm using the unofficial 2.4 for Windows and try to connect from an Android-app using the Java-driver. All via ddns.net/DUC with forwarded ports.

On the client side I launch it using Dispatchers.IO as context for the Couritine, so that the network operation won't happen on the main thread.

import com.rethinkdb.RethinkDB;
import com.rethinkdb.net.Connection;
import kotlinx.coroutines.Dispatchers
import kotlinx.coroutines.launch
import com.rethinkdb.gen.exc.ReqlError;

//... a normal Fragment or Activity

val scope = rememberCoroutineScope() //used in Jetpack Compose for more or less local scopes
val r = RethinkDB.r

scope.launch(Dispatchers.IO) {
    try{
        r.connection().hostname("my-ddns.net-link-goes-here").port(28015).connect()
    }catch (e: ReqlError){
        Log.w("myFragment", "ERR: $e")
    }
}

Trying to establish a connection results in:

com.rethinkdb.gen.exc.ReqlDriverError: java.security.spec.InvalidKeySpecException: Could not generate secret key

What exactly causes this? Any way to resolve it?

Giving context about your java and environment in general will probably help?

PXNX commented 3 years ago

I'm using Kotlin 1.4.32 for this and Android-Studio 4.2 (shouldn't really make a difference). It's run on various virtual and physical devices running Android 9-11.

@PXNX Am Doing Exactly Same Steps , But Getting Same error in Android , its Working fine in Normal Java Project and in Flutter also Dart version Working Fine ,But Getting This in Android only , my tetsing Android Version is 10, Found Any Solution??

PXNX commented 3 years ago

@rohitsangwan01 Seems like you have to add a user to it.

for example: r.connection().hostname("some-url.com").port(42069).user("bob", "salat").connect()

This was not mentioned in the guide though :(

Find the full code here: https://github.com/PXNX/RethinkAndroidTest

I also recommend you to use reQL-pro to edit your database

@PXNX ,Thanks man, so is it working for you in Android ??,. Just Checked , Great ,its Working Fine , waisted almost 2 hours , they should atleast write a line in docs about t , Thanks again man
