Finally I think I solved this problem! :-)

This is the patch I'm going to send to the `ssl_openssl_lib` authors: http://pastebin.com/VgSpnwxB .
In short, I just removed the RAND_screen() call, generated a random buffer using RAND_bytes() (based on https://wiki.openssl.org/index.php/Random_Numbers#Software) seeding via RAND_add().
Thanks a lot for the help, dudes! :-)

Thanks for sharing the links, I'm going to check them.The original code call RAND_screen() only once in the app initialization, so can I replace it by RAND_add()? (I'm newbie on SSL)I've noticed the application is just a HTTP client consuming some web services via HTTPS. It doesn't call explicitly any OpenSSL random function, so I think it uses the default OpenSSL configurations.On Sat, Dec 3, 2016 at 3:42 PM, Jeffrey Walton <noloader@xxxxxxxxx> wrote:[...]Also see https://wiki.openssl.org/index.php/Library_Initialization and

The short of it is, you should stop relying on auto-initialization of
the RNG, and seed it yourself with a call to `RAND_add`.
