From 98ee75439d7e844de6c063a4be5bd09b3cc9db53 Mon Sep 17 00:00:00 2001 From: Matt Caswell Date: Tue, 22 Sep 2015 11:11:24 +0100 Subject: Update the dasync engine to add a pipeline cipher Implement aes128-cbc as a pipeline capable cipher in the dasync engine. As dasync is just a dummy engine, it actually just performs the parallel encrypts/decrypts in serial.
