Thank you for submitting homework task-2 in Crypto-Academy.

Through keystore file, you can restore your wallet again if you have backed up it at the time installing wallet.

A keystore wallet alone is not a private key. So when you recover your wallet using the Keystore File you also need to enter the password(set by you in the previous installation). So be careful with your password, better save it just like you save your private key(if you are using a Keystore file).

Keystore File+Password(set by you) ~ Private Key

Your own experience with a wallet and the step-by-step process would be the ideal way to take on a task like this. In that process, you also develop a better understanding of a particular dApp/Wallet.

Thank you.
