Need RSA private or public key error

[mahesh-vidhate]

I am getting this error on Samsung Galaxy S8 Android device, for other Android devices, it works. This error occurs while either setting or getting the key stored in Keystore. following is my code -

code to set key

exports.SET_KEY = (randomKey) => { RNSecureKeyStore.set(KEY_STORE_KEYNAME, randomKey) .then((res) => { console.log(res); }, (err) => { console.log("SET_KEY",err); }); }

code to get key

exports.GET_KEY = (success, fail) => { RNSecureKeyStore.get(KEY_STORE_KEYNAME) .then((res) => { console.log(res); success(res) }, (err) => { console.log('GET_KEY', err); fail(KEY_NOT_FOUND) }); }

I am getting error as,

Error: {"code":9,"api-level":26,"message":Need RSA private or public key} at createErrorFromErrorData (NativeModules.js:146) at NativeModules.js:95 at MessageQueue.invokeCallback (MessageQueue.js:397) at MessageQueue.js:127 at MessageQueue.guard (MessageQueue.js:297) at MessageQueue.invokeCallbackAndReturnFlushedQueue (MessageQueue.js:126) at debuggerWorker.js:72

@mahesh-vidhate I am also getting this error on a Galaxy s9, but not every time. I check for an item in the store on initial app load, and that's the one where I am getting the error. Did you ever find a solution?

@ostaron Apologise for the delay. To solve this issue you need clear the app data manually from the setting. You may find that from setting -> installed apps -> youAppName. This is usually happening because after uninstalling the app from the device, OS still keeps some data of it. So when you install the same app again, OS failed to update your keystore with new keys you are trying to store. To solve this issue I put the following code in the manifest to remove all data of app on uninstallation. <manifest xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" package="..."> <application android:name=".MainApplication" android:label="@string/app_name" android:icon="@mipmap/ic_launcher" android:theme="@style/AppTheme" android:allowBackup="false" tools:replace="android:allowBackup"> . .

You can also uninstall the app and run CCleaner. It accomplishes the same thing.
