Dropbear ssh hardening guide addition #159

Closed graysky2 closed 1 year ago

graysky2 commented 2 years ago

The current release of dropbear can be hardened by building it adding the following three lines to localoptions.h:

#define DROPBEAR_RSA_SHA1 0
#define DROPBEAR_DH_GROUP14_SHA1 0
#define DROPBEAR_SHA1_HMAC 0

Wondering if you would like to add this to your hardening guide.

I've updated the website (https://www.ssh-audit.com/hardening_guides.html) and the wiki (https://github.com/jtesta/ssh-audit/wiki/Dropbear-2022.83) with this. Thanks for contributing!
