string radius_demangle_mppe_key (resource radius_handle, string mangled)
string radius_demangle_mppe_key
Returns: string, FALSE on error.
When 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.
