Scenario

A Ravens key checker builds the correct password from an array of numbers instead of storing it as text. Reading the logic and decoding the numbers recovers the flag. The artifact is inert: it reads input and prints a verdict only — no network, no writes, no persistence.

What you are looking at

You download rev-strings.zip with keygen.js, a script that accepts the right password and builds it from a number array.

Goal

Read the logic and decode the number array to recover the password, the flag.

What counts as solved

You enter the correct flag.

Method checklist

Tick each step as you work through it. The steps are the method, not the answer.

Open keygen.js and read the PARTS array.
Understand they are character codes.
Convert them to text.
Read the flag.
