SAE (Simultaneous Authentication of Equals) takes place during authentication, and followed by EAPoL/4-way handshake. This module handles the entire SAE commit/confirm exchange. This was done similar to eapol. SAE begins when sae_register is called. At this point a commit message will be created and sent out which kicks off the SAE authentication procedure. The commit/confirm exchange is very similar to EAP-PWD, so all the ecc utility functions could be re-used as-is. A few new ecc utility functions were added to conform to the 80211 'blinding' technique for computing the password element.
