## Summary Implements [RFC 3748](https://tools.ietf.org/html/rfc3748) EAP-GTC authentication. EAP-GTC allows EAP authentication using a plaintext password. Does not provide keying material for 802.11i, so cannot be used for WPA/2-Enterprise authentication unless wrapped in another method such as EAP-TTLS.
