Each key type may use a different label to bind the key usage into the generated material. The caller is responsible for freeing the returned buffer. Note: To provide the RFC 5705 context, the context variable must be non-NULL.

eap_get_config_password2 - Get password from the network configuration @sm: Pointer to EAP state machine allocated with eap_peer_sm_init() @len: Buffer for the length of the password @hash: Buffer for returning whether the password is stored as a NtPasswordHash instead of plaintext password; can be %NULL if this information is not needed Returns: Pointer to the password or %NULL if not found

eap_peer_tls_process_helper - Process TLS handshake message @sm: Pointer to EAP state machine allocated with eap_peer_sm_init() @data: Data for TLS processing @eap_type: EAP type (EAP_TYPE_TLS, EAP_TYPE_PEAP, ...) @peap_version: Version number for EAP-PEAP/TTLS @id: EAP identifier for the response @in_data: Message received from the server @in_len: Length of in_data @out_data: Buffer for returning a pointer to the response message Returns: 0 on success, 1 if more input data is needed, 2 if application data is available, or -1 on failure This function can be used to process TLS handshake messages. It reassembles the received fragments and uses a TLS library to process the messages. The response data from the TLS library is fragmented to suitable output messages that the caller can send out. out_data is used to return the response message if the return value of this function is 0, 2, or -1. In case of failure, the message is likely a TLS alarm message. The caller is responsible for freeing the allocated buffer if *out_data is not %NULL. This function is called for each received TLS message during the TLS handshake after eap_peer_tls_process_init() call and possible processing of TLS Flags field. Once the handshake has been completed, i.e., when tls_connection_established() returns 1, EAP method specific decrypting of the tunneled data is used.

If this is the first fragment of a TLS message, the TLS reassembly code is initialized to receive the indicated number of bytes. EAP-TLS, EAP-PEAP, EAP-TTLS, and EAP-FAST methods are expected to use this function as the first step in processing received messages. They will need to process the flags (apart from Message Length Included) that are returned through the flags pointer and the message payload that will be returned (and the length is returned through the len pointer). Return values (ret) are set for continuation of EAP method processing. The caller is responsible for setting these to indicate completion (either success or failure) based on the authentication result.
