The radcli library is a library for writing RADIUS Clients. The library's approach is to allow writing RADIUS-aware application in less than 50 lines of C code. It was based originally on freeradius-client and radiusclient-ng and is source compatible with them.
For the development of the openconnect VPN server, I needed a simple library to allow using radius for authentication and accounting without having to understand the internals of radius. Such library was the freeradius-client library, but was undocumented, had too much legacy code centered around radlogin, a tool which is of no significance today, was IPv4-only and had no releases for several years, and zero tests.
This library addresses these shortcomings, adds a test suite and test driven development, adds package management via pkg-config, adds support for TCP, TLS and DTLS, provides documentation of the API, and will include any new features for the task. It is provided as a shared library in case it is useful to other projects as well, and is also made source compatible with radiusclient-ng and freeradius-client.
