realm WriteCopyTo backup works - opening file failes with decryption failed

Goals

When I try to open encrypted backed up realm file from Realm studio, with the same encryption key that it was configured it says decryption failed.

Unable to open a realm at path 'C:\Users\Foo\Desktop\123.realm': Realm file decryption failed.

Expected Results

Should be able to open realm file.

Actual Results

decryption failes even though file was not suspended realm file.

Unable to open a realm at path 'C:\Users\Foo\Desktop\123.realm': Realm file decryption failed.

Steps to Reproduce

Code Sample

Using

            var realmInstance = Realm.GetInstance(config);
            var configNew = new RealmConfiguration(Path.GetTempFileName())
            {
                EncryptionKey = realmInstance.Config.EncryptionKey
            };
            File.Delete(configNew.DatabasePath);

            realmInstance.Write(() =>
            {
                realmInstance.WriteCopy(configNew);
            });
            realmInstance.WriteCopy(configNew);

Key string planKey= BitConverter.ToString(realmInstance.Config.EncryptionKey).Replace("-", string.Empty);

Another method tried to backup realm file.

realmInstance.Dispose();

And

Copying the file at realmInstance.Config.DatabasePath with Java native stream method.

Still the same error

Yes, you can open the file on the same Android device.

The way Realm encryption works is dependent on the size of a memory page - usually that’s different between 32bit and 64bit devices (or more specifically the architecture of the app, not the device).

I supposed you can open the same encrypted realm file created on a 64bit Android device on a 64bit iOS device, provided your app is running in the same architecture in both cases, but if you want to share encrypted realm files between devices you should really take the hardware difference into account.

Unencrypted realm files can be open on any platform, regardless of where they were first created.
