DOS Exploit

[Tostino]

Hey, just wanted to let you know I've gotten reports from users of my library: Nbvcxz that are getting a DOS every so often by specifically crafted passwords.

I even found a tool created by a government contractor used for issuing a DOS against programs using libraries containing the vulnerable (to combination explosion) algorithms from the original zxcvbn implementation:

• https://github.com/twosixlabs/acsploit
• acsploit GoSimpleLLC/nbvcxz#60

I've solved this by implementing a maxLength type configuration...but that isn't totally done yet as I feel like I still need to have it do dictionary checks against the full-length password without any transformations. Working on finishing that feature and putting out a release.
