## Effect of Compromised Dice on Dice Generated Passphrases

The 2016 fundraiser for the
Electronic Frontier Foundation
provided 6-sided dice to their donors.
These dice are supposed to be used to generate
diceware passphrases.

Their fundraising campaign was so popular that they didn't have enough
dice to give to all of their donors. This made me wonder... if someone
was able to convince the factory that makes the EFF dice to make them
weighted, how much would this help.

The page below computes the probabilities for each of the words
from the new EFF long wordlist given dice that have the probabilities
from the inputs below. At the bottom of the page it lists the most probable
words given the weighting that you choose.

The expected number of guesses for a single word that is reported is the
number of guesses that would have to be made, if the attacker was going
down the list from most-probable to least-probable, before they had a
greater than 50% chance of having guessed it already.
