From afeb62f01ad6e610cd19dcde0ceffc018b3247ec Mon Sep 17 00:00:00 2001
From: Eneas U de Queiroz <cote2004-github@yahoo.com>
Date: Wed, 6 Jun 2018 18:05:33 -0300
Subject: [PATCH] Remove API deprecated in openssl 1.1
With openssl 1.1, we do not call OpenSSL_add_all_algorithms(), as
library initialization is done automatically.
Functions RAND_pseudo_bytes and RSA_generate_key were deprecated as
well.
Also, we need to #include <openssl/bn.h> for BN_num_bytes().
