libdkim++ is a lightweight and portable DKIM (RFC4871) library for *NIX, supporting both signing and DMARC/SDID/ADSP verification sponsored and used by Halon Security's (http://halon.io) SMTP platform. libdkim++ has extensive unit test coverage and aims to fully comply with the current RFC.
This library requires CMake (http://www.cmake.org/) to compile, and depends on OpenSSL (which is normally shipped with *NIX distributions).
$ cmake .
$ make && make install
You might need to add some packages, like a C++ compiler and cppunit
which can be done by running pkg_add -r cppunit,
apt-get install cppunit or yum install cppunit-devel depending
on operating system.
- cmake
- pkg-config
- cppunit
- libssl-dev
Because some systems (like OpenBSD) lacks a reentrant resolver, this library might not be thread-safe on all platforms.
libdkim++ has extensive unit test coverage and aims to fully comply with the current RFC.
$ make test
which should result in this output:
