From 1e80e0449248edb77b0fb9853f4a3404a599e207 Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Thu, 22 Dec 2005 18:55:59 +0100 Subject: [PATCH] sha1_to_hex: properly terminate the SHA1 sha1_to_hex() returns a pointer to a static buffer. Some of its users modify that buffer by appending a newline character. Other users rely on the fact that you can call printf("%s", sha1_to_hex(sha1)); Just to be on the safe side, terminate the SHA1 in sha1_to_hex().
