radius_demangle_mppe_key — Derives mppe-keys from mangled data
$radius_handle, string $mangled): stringWhen using MPPE with MS-CHAPv2, the send- and recv-keys are mangled (see ? RFC 2548), however this function is useless, because I don't think that there is or will be a PPTP-MPPE implementation in PHP.
radius_handleThe RADIUS resource.
mangledThe mangled data to demangle
Returns the demangled string, or false on error.
