Detailed Description

EAP-TLS/PEAP/TTLS/FAST server common functions.

Function Documentation

u8* eap_server_tls_derive_session_id	(	struct eap_sm *	sm,
		struct eap_ssl_data *	data,
		u8	eap_type,
		size_t *	len
	)

Derive a Session-Id based on TLS data.

Parameters

sm	Pointer to EAP state machine allocated with eap_peer_sm_init()
data	Data for TLS processing
eap_type	EAP method used in Phase 1 (EAP_TYPE_TLS/PEAP/TTLS/FAST)
len	Pointer to length of the session ID generated

Returns

Pointer to allocated Session-Id on success or NULL on failure

This function derive the Session-Id based on the TLS session data (client/server random and method type).

The caller is responsible for freeing the returned buffer.
