From 5028bf628c7ebfb85d14ec7dc296b264a1c3bcd3 Mon Sep 17 00:00:00 2001 From: "brian m. carlson" Date: Sun, 26 Mar 2017 16:01:23 +0000 Subject: Define new hash-size constants for allocating memory Since we will want to transition to a new hash at some point in the future, and that hash may be larger in size than 160 bits, introduce two constants that can be used for allocating a sufficient amount of memory. They can be increased to reflect the largest supported hash size.
