So the only way to fix that problem, I guess, is to find clever ways to try using that same hash to try and reproduce the complicated output."Įssentially, you go phishing.

And because there's no company interface, there's no one that can help you reset that password if you forget it. "You say, I'm creating a wallet with the password 'banana', and it turns into this mess of a key. "With Ethereum, because it's decentralized, you actually do all this on your own computer and it doesn't even touch the internet," Dougherty told Engadget. However, as Dougherty's clients have discovered, Ethereum's security system is tight. The idea is that it's impossible to reverse-engineer the hash to unlock a user's base password, though a handful of algorithms have been compromised over the years, including MD5 and SHA1. To get specific, Ethereum wallets use a password-based key derivation function, meaning users input a unique password they can (theoretically) remember, and in return, they receive a key that serves as a unique, secure authorization code. There's no customer support hotline for Ethereum, no security questions to answer, no "Forgot password?" link.Ĭryptocurrency security relies on hashing algorithms that transform a traditional password, such as "banana$123," into a unique string of numbers and letters, called a hash. These people are, essentially, shit out of luck.
Meanwhile, back at home, Dougherty is the shepherd of a program that's constantly running down ways to break into other people's cryptocurrency wallets.ĭougherty works with folks who have lost, forgotten or incorrectly written down their Ethereum passwords, locking themselves out of their wallets and forfeiting the digital cash that's lurking within.
