Patrick Sean Klein 65a1d1b0f7 Limit zxcvbn entropy estimation length
Limit the use of zxcvbn based password entropy estimation to 256 bytes. After this threshold, the average per-byte entropy from the zxcvbn calculation is added for each additional byte. In practice, this produces a slightly higher entropy calculation for purely randomized passwords than zxcvbn would normally calculate. However, the time to calculate is capped leading to a much better user experience and removing unnecessary calculations.
