MS-CHAPv1 MPPE-keys). - Added rad_demangle_mppe_key() for demangling mppe-keys (needed for MPPE-keys). - Added some typecasts for avoiding compiler warnings. - Fix: better handle wrong usage of the lib (if the programmer has not called rad_create_request() but rad_put_*(), then a weird error message was returned). - Added a new function for putting the Message-Authenticator. - Verify the Message-Authenticator, if it was found inside a response packet and silently drop the packet, if the validation failed. - Implicitly put the Message-Authenticator, if the EAP-Message attribute was added. - Added some missing defines. Submitted by: Michael Bretterklieber PR: 46555
