From 94127599252d85e85571ecde740ea97e59e4bede Mon Sep 17 00:00:00 2001 From: "brian m. carlson" Date: Sat, 22 Feb 2020 20:17:30 +0000 Subject: repository: require a build flag to use SHA-256 At this point, SHA-256 support is experimental and some behavior may change. To avoid surprising unsuspecting users, require a build flag, ENABLE_SHA256, to allow use of a non-SHA-1 algorithm. Enable this flag by default when the DEVELOPER make flag is set so that contributors can test this case adequately.
