From ce43b2e351c860bc50151b3ddc190b92a7536c8e Mon Sep 17 00:00:00 2001 From: Ofer Heifetz Date: Mon, 28 May 2018 11:03:27 +0200 Subject: crypto: inside-secure - increase minimum transfer size The token size was increased for AEAD support. Occasional authentication fails arise since the result descriptor overflows. This is because the token size and the engine minimal thresholds must be in sync.
