From 9467a3150cf4afca638673e099af71e8c493a3a0 Mon Sep 17 00:00:00 2001 From: Ard Biesheuvel Date: Tue, 2 Jul 2019 21:41:46 +0200 Subject: crypto: lib/aes - export sbox and inverse sbox There are a few copies of the AES S-boxes floating around, so export the ones from the AES library so that we can reuse them in other modules.
