radius_demangle_mppe_key — Derives mppe-keys from mangled data

### Descripción

radius_demangle_mppe_key(resource `$radius_handle`, string `$mangled`): string

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.

### Parámetros

  El recurso RADIUS.

`mangled`

  The mangled data to demangle

### Valores devueltos

Returns the demangled string, or `false` on error.
