SPA requires only a single \ encrypted packet in order to communicate various pieces of \ information including desired access through a Netfilter policy \ and/or complete commands to execute on the target system. By \ using Netfilter to maintain a 'default drop' stance, the main \ application of this program is to protect services such as OpenSSH \ with an additional layer of security in order to make the \ exploitation of vulnerabilities (both 0-day and unpatched code) \ much more difficult. The authorization server passively monitors \ authorization packets via libcap and hence there is no 'server' to \ which to connect in the traditional sense. Access to a protected \ service is only granted after a valid encrypted and non-replayed \ packet is monitored. This port installs the client side script \ that you run to gain access to a Linux box. checksums rmd160 9c8ab4ad0849c893742b5bb3bbb424b2b6fb0d35 \ sha256 a15b721611a0f3b8b8915b388a32f46d4b9bba577d879bc4f1677786b13292a0 depends_lib-append port:gnupg \ port:gpgme use_autoreconf yes configure.args-append --disable-server test.run yes test.target check
