From 33f1273f9f1e41c1c7f42732dd9430e40476abc3 Mon Sep 17 00:00:00 2001 From: Nicola Corna Date: Sun, 13 Aug 2017 19:38:41 +0200 Subject: tint: Use the current time as random seed Previously the random seed was fixed, which led to the same sequence of blocks for each run. Now that libpayload has time(), no change is needed in the function rand_init() of tint.
