[1859, Alfred Holbrook, “Theoretical Arithmetic”, in The Normal: or, Methods of Teaching the Common Branches, […], New York, N.Y.: […] A[lfred] S[mith] Barnes & Burr, […], →OCLC, page 306Unlike most auction sales delinquent tax property is sold to the lowest instead of the highest bidder. The man who will pay the taxes for the smallest portion of the property in question is the successful man, and the figure at which the bidders sometimes bid in the property is enough to cause the treasurer and his accountants to become fit subjects for the insane hospital. County Treasurer Cropper has a list of the limits to which the bidders may go, carried down past the vigintillions and even decamadillions. To give the reader something of an idea of the proportions of the figures sometime resorted to, we will state that the decamadillion is the highest figure known in mathematics, but the bidders do not stop at this as a rule. […] Several bids were made of the vigintillionth down to the eighth, sixth and fourth power. The list of numerals kept by the treasurer for this occasion is as follows: Hundreds, thousand,^([sic]) millions, billions, trillions, quadrillions, quintillions, sextillions, septillions, octillions, nonillions, decillions, undecillions, duodecillions, tradecillions, quatuordecillions, quindecillions, sextecillions,^([sic]) sepdecillions, octodecillions, noendecillions,^([sic]) vigindecillions,^([sic – meaning vigintillions]) trigindecillions, quadroquintillions, quinquagintillions, sexagintillions, septuagintillions, octogentillions, novengentillions, centamadecillions, decamadillions.

This is long after the heat death of the universe, so our hacker is going to get very bored waiting around for that long. In this case, PBKDF2 would make it infeasible to crack the password.
