Dropbear 2019.78 is available and functions correctly on both FreeBSD 12-S and HardenedBSD 12-S. You will need to modify Makefile for PORTVERSION= 2019.78 rm /usr/ports/security/dropbear/files/patch-configure Twofish has been disabled by default, according to the change log because it needs to be tested against other implementations. For me, twofish is a feature. So you may wish to implement something like post-patch: @${REINPLACE_CMD} -e "/_TWOFISH/s, 0, 1,g" \ ${WRKSRC}/sysoptions.h ${WRKSRC}/default_options.h
There's an option to use twofish. I will update the port, though.
