From afe36b58bb77012f94b19213ed9602c2eb9fd420 Mon Sep 17 00:00:00 2001
From: Niclas Eklund <nick@erlang.org>
Date: Tue, 19 Apr 2011 13:35:29 +0200
Subject: Renamed the function strong_rand_uniform to strong_rand_mpint. Added
 some checks in crypto.erl and crypto.c. Changed ssh_bits to use
 strong_rand_mpint.
