/******************************************************************************/ 

is there a way I can change the key used so every client will have their unique encryption key that will change every login?

can I add this to the Connection.h file?

PHP Code:
void changeKey(Secure newKey){_secure newKey;} 

then add in my auth function (after the server sent the key to the client) on both client and server

SERVER
PHP Code:
Secure newKey;
FREP(32)newKey.key[i]=rnd(0xff);
client(current).connection.changeKey(newKey); 

CLIENT
PHP Code:
Secure newKey;
FREP(32)newKey.key[i]=Server.data.getByte();
Server.changeKey(newKey);

every Connection always uses unique encryption
