Can you point to a specification saying how this hashing works?
A---------->B(nsis server)--------->C(radius server) User A generates a large buffer which contains various Authentication Attributes, A hash of this string is generated using MD5 algorithm with a key known to both users A and C, This string is appended to the original string and sent over the network, Node B get this string and it extract various session attributes from this string. The attributes extracted should be used to construct the diameter message using freeradius client library.

Is there a way to do this i.e. how to generate a AAA message with the information available i.e. a string, its keyed hash and User A's id ? Assuming that the Radius server has keys of all legitimate users.
Yes. http://www.freeradius.org/freeradius-client/ Alan DeKok. -- http://deployingradius.com - The web site of the book http://deployingradius.com/blog/ - The blog
