    # checksummed address
    print $key->address->prefixed;
    my $keyfile = Blockchain::ethereum::Keystore::Keyfile->new;

    $keyfile->import_key($key);
    $keyfile->write_to_file("...");

Importing a keyfile and changing the password:

    my $keyfile = Blockchain::Ethereum::Keystore::Keyfile->new;
    my $password = "old_password";
    $keyfile->import_file("...", $password);
    $keyfile->change_password($password, "newpassword");
    $keyfile->write_to_file("...");

Signing a transaction:

    my $transaction = Blockchain::Ethereum::Transaction::EIP1559->new(
        ...
    );

    my $keyfile = Blockchain::Ethereum::Keystore::Keyfile->new;
    $keyfile->import_file("...");
    $keyfile->private_key->sign_transaction($transaction);

Exporting a keyfile private key:

    my $keyfile = Blockchain::Ethereum::Keystore::Keyfile->new;
    $keyfile->import_file("...");

    # private key bytes
