Challenge 1 Solution:

Find typo in private key

The brute-force-find-typo.js script will brute force check every character and try replacing it with all the other valid Base-58 characters. Once it finds a valid WIF-encoded private key, it prints out the answer.

Usage:

node brute-force-find-typo.js 5Jhacv9gEyp7yosCeq1zgRRQSitGZZ3Z2NbgKG9BFXHW16iYU4z

Once you find the valid WIF private key, you can import it into a wallet like Electrum
