From 797f2836c48f9ba2446629ae4b6867ca1a5ea512 Mon Sep 17 00:00:00 2001
From: Taahir Ahmed <ahmed.taahir@gmail.com>
Date: Wed, 30 Mar 2016 11:23:54 -0300
Subject: [PATCH 1/2] crda: support python 3 in utils/key2pub.py
utils/key2pub.py can now be run under either python 2.7 or python 3.x.
This required some minor syntactical changes as well as switching from
M2Crypto to pycrypto, since M2Crypto doesn't support python 3.x.
In addition, some errors in the generated source file keys-ssl.h are
fixed:
* The correct OpenSSL header for BN_ULONG is included.
* The generated constants are given the 'ull' suffix to prevent
warnings about constants that are too large.
[Gustavo: don't call /utils/key2pub.py since that doesn't compute]
