Macro Definition Documentation

◆ NTOR_ONIONSKIN_LEN

#define NTOR_ONIONSKIN_LEN   84

Length of an ntor onionskin, as sent from the client to server.

Definition at line 23 of file onion_ntor.h.

◆ NTOR_REPLY_LEN

#define NTOR_REPLY_LEN   64

Length of an ntor reply, as sent from server to client.

Definition at line 25 of file onion_ntor.h.

Typedef Documentation

◆ ntor_handshake_state_t

State to be maintained by a client between sending an ntor onionskin and receiving a reply.

Definition at line 1 of file onion_ntor.h.

Function Documentation

◆ ntor_handshake_state_free_()

void ntor_handshake_state_free_ ( ntor_handshake_state_t state)

Free storage held in an ntor handshake state.

Definition at line 38 of file onion_ntor.c.

◆ onion_skin_ntor_client_handshake()

int onion_skin_ntor_client_handshake ( const ntor_handshake_state_t handshake_state,
const uint8_t *  handshake_reply,
uint8_t *  key_out,
size_t  key_out_len,
const char **  msg_out 
)

Perform the final client side of the ntor handshake, using the state in handshake_state and the server's NTOR_REPLY_LEN-byte reply in handshake_reply. Generate key_out_len bytes of key material in key_out. Return 0 on success, -1 on failure.
