Dapphp\Radius is a pure PHP RADIUS client for authenticating users against a RADIUS server in PHP. It currently supports basic RADIUS auth using PAP, CHAP (MD5), MSCHAP v1, and EAP-MSCHAP v2. The current 2.5.x branch is tested to work with Microsoft Windows Server 2012 to 2019 Network Policy Server and FreeRADIUS 2 and above.

PAP authentication has been tested on: * Microsoft Radius server IAS * Mideye RADIUS Server * Radl * RSA SecurID * VASCO Middleware 3.0 server * WinRadius * ZyXEL ZyWALL OTP

The PHP openssl extension is required if using MSCHAP v1 or v2. For older PHP versions that have mcrypt without openssl support, then mcrypt is used.
