# Overview

{% hint style="warning" %}
The **Prover private key** in the keys.yml file is encrypted using the Advanced Encryption Standard (AES), and therefore cannot be directly imported into the Qrim Wallet.\
\
If you want to bridge $QUIL to $wQUIL, please create an address with both the peerPrivKey and Prover private key using Qrim Wallet, and then send $QUIL to this address for bridging
