Hi,

I am  sending the client Hello message ,when Freeradius recieves the Client
hello it sends the Server Hello message with following data. If you see the
data
it contains

Signature Hash Algorithm Hash:SHA1 (2)

>From where does the freeradius populate that data, i want that Freeradius
should
send the SHA256 Hash algo value in Server Hello message..
