From 54c93cb4afc932ab125a59464bb52e04f9c36575 Mon Sep 17 00:00:00 2001 From: Jeff King Date: Thu, 22 Aug 2013 19:12:42 -0400 Subject: [PATCH] test-sha1: add a binary output mode The test-sha1 helper program will run our internal sha1 routines over its input and output the 40-byte hex sha1. Sometimes, however, it is useful to have the binary 20-byte sha1 (and it's a pain to convert back in the shell). Let's add a "-b" option to output the binary version.
