Title:
On Singh et. al.'s “Collatz Hash”

Authors: Joe Doyle

Abstract:

Singh et. al. recently uploaded a preprint describing a new hash function inspired by the Collatz Conjecture. After performing some cursory tests, the proposed function appears to be completely unsuitable for cryptographic purposes, and should not be used.
