From 0dff81c6a5876172bc1d4725a7a07fddd9d1f369 Mon Sep 17 00:00:00 2001 From: Willy Tarreau Date: Tue, 15 Jul 2014 21:34:06 +0200 Subject: [PATCH 4/5] BUG/MINOR: http: base32+src should use the big endian version of base32 We're using the internal memory representation of base32 here, which is wrong since these data might be exported to headers for logs or be used to stick to a server and replicated to other peers. Let's convert base32 to big endian (network representation) when building the binary block. This mistake is also present in 1.5, it would be better to backport it.
