@hashseed hashseed commented Oct 4, 2018

This serves as mitigation for the so-called HashWick vulnerability.

Original commit messages:

  commit 3833fef57368c53c6170559ffa524c8c69f16ee5
    Author: Yang Guo <yangguo@chromium.org>
    Date: Thu Sep 20 11:43:13 2018

    Refactor integer hashing function names

    We now clearly differentiate between:
    - unseeded hash for 32-bit integers
    - unseeded hash for 64-bit integers
    - seeded hash for 32-bit integers
    - seeded hash for strings
