InvalidKeyException thrown when attempting to restore from re-encrypted backup #9

Closed crass closed 3 years ago

crass commented 3 years ago

I followed the instructions in the section Wifi Key Import and copied the same wifi config from the successful decryption. I used the same key to re-encrypt as I used to decrypt. Any ideas on what might be going on?

Here's the relevant logcat:

Missed the line with Caused by: android.security.KeyStoreException: Device locked ... perhaps this should be mentioned in the readme
