From e8e35982845f36e714b915350eaf6855487aa0e8 Mon Sep 17 00:00:00 2001 From: Jakob Unterwurzacher Date: Tue, 28 Sep 2021 17:43:36 +0200 Subject: -init: suggest xchacha if we don't have AES accel Example on Raspberry Pi 4: $ ./gocryptfs/gocryptfs -init $(mktemp -d) Notice: Your CPU does not have AES acceleration. Consider using -xchacha for better performance. Choose a password for protecting your files.
