From e4b47f7f19392e3be604e44f6999de2bc9e7ecf3 Mon Sep 17 00:00:00 2001 From: Nick Mathewson Date: Wed, 16 May 2018 11:07:48 -0400 Subject: [PATCH] Update documentation for PEM callback: error is now -1. In previous versions of OpenSSL, the documentation for PEM_read_* said: The callback B return the number of characters in the passphrase or 0 if an error occurred. But since c82c3462267afdbbaa5, 0 is now treated as a non-error return value. Applications that want to indicate an error need to return -1 instead.
