radius_demangle_mppe_key - Derives mppe-keys from mangled data

SYNOPSIS
       string radius_demangle_mppe_key (resource  $radius_handle, string  $mangled)

DESCRIPTION
	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.

RETURN VALUES
	Returns the demangled string, or FALSE on error.
