radius_demangle_mppe_key — Derives mppe-keys from mangled data
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.
Returns the demangled string, or
FALSE on error.
