Brainwallets are a way of storing cryptocurrency using private keys generated from a passphrase one memorizes. They are notoriously insecure because the average person cannot easily memorize passphrases of sufficient length to avoid being cracked by a computer. The unofficial time of death for brainwallets is August 7th, 2015 when Ryan Castellucci released his "Brainflayer" brainwallet cracker at Defcon 23.

This passphrase is commonly known from the xkcd cartoon shown to the right. The cartoon claims an easy to memorize 4 word passphrase has more security (entropy) than a passphrase with 11 characters based on an uncommon English language word. We will avoid any debate on the truth to these claims because what we do know is, with a tool like Brainflayer, cryptocurrency secured with any 4 word passphrase is not safe and likely to be stolen.

To solve this challenge you must use the passphrase to recreate the private key for this challenge's Bitcoin address using a brainwallet generator. Visit the Solve tab, get the "string to sign" from the form and sign it with the private key in the software of your choice.
