I figured it was unlikely google would make such a mistake, so I looked at the docs. They use public key cryptography to generate a private shared secret that is hashed alongside the message. This prevents the brute force hash attack.
Awesome! Thanks for looking this up, instead of just speculating.
Btw, in some sense this is exactly the same stuff you'd have to do to make committing to a single-bit work. Or encrypting a short message, in a way that's not easy to crack.
