From c347ece05a7fdbf50d76cb136b9ed45caed333f6 Mon Sep 17 00:00:00 2001
From: Joseph Reynolds <joseph.reynolds1@ibm.com>

Subject: [PATCH] dropbear: new feature: disable-weak-ciphers
This feature disables all CBC, SHA1, and diffie-hellman group1 ciphers
in the dropbear ssh server and client since they're considered weak ciphers
and we want to support the stong algorithms.
Upstream-Status: Inappropriate [configuration]
