 ### Password Cracking
 
-Besides the [academic use case](https://password-guessing.org) of [improving proabilistic password modeling](https://hal.archives-ouvertes.fr/hal-01112124/file/omen.pdf), [estimating guess numbers](https://github.com/RUB-SysSec/Password-Guessing-Framework) or [password strength](https://www.internetsociety.org/sites/default/files/06_3.pdf), one might be interested in cracking hashed (unknown) passwords.
