From a3667c316ae60ef454fb804221c3ca44af30a9aa Mon Sep 17 00:00:00 2001 From: Matt Caswell Date: Wed, 16 Sep 2015 12:28:03 +0100 Subject: Add async sub-library to libcrypto Provides support for running asynchronous jobs. Currently this is completely stand alone. Future commits will integrate this into libssl and s_server/ s_client. An asynchronous capable engine will be required to see any benefit from this capability.
