= Introduction =

Since version 2.3, OpenVPN can be built using PolarSSL as it's crypto backend, instead of OpenSSL. See [https://polarssl.org/] for more information on PolarSSL.

= Limitations compared to OpenSSL =

Note that the PolarSSL variant of OpenVPN does not support the same featureset as the OpenSSL variant. The most prominent differences are listed in the latest [https://github.com/OpenVPN/openvpn/blob/master/README.polarssl README.polarssl].

= Building the PolarSSL-enabled OpenVPN =

OpenVPN 2.3 has full PolarSSL support. Get the sources from [http://openvpn.net/index.php/open-source/downloads.html the download page], or get the most recent (potentially unstable) code [https://github.com/OpenVPN/openvpn from github].

To build using polarssl:
{{{
./configure --with-crypto-library=polarssl
make
make install
}}}
