| 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] |
