This project implements an Unlock PublicLock Hook that can be used on Locks smart contracts to ensure that users who are purchasing a key from a lock have entered the right password on the frontend application.
This process is secured and cannot be bypassed by calling the contract directly as the password is used to submit the transaction on-chain.
When the user enters a password on the frontend application, the password is used to generate a private key that is then used to sign the recipient's address. That signature is passed as the data argument on the purchase call.
A lock manager can set the right signer based on the password for a lock using setSigner.
The Unlock Protocol team has deployed and verified a version of this hook on the following networks:
From the Unlock Dashboard, go to "Settings", then select "Advanced" and finally "Hooks". Check this Guide for more details.
