Detailed Description

Service side introduction point.

Definition at line 50 of file hs_service.h.

Field Documentation

◆ auth_key_kp

ed25519_keypair_t auth_key_kp

◆ base

Top level intropoint "shared" data between client/service.

Definition at line 52 of file hs_service.h.

Referenced by describe_intro_point().

◆ blinded_id

Blinded public ID for this service, from this intro point's active time period.

Definition at line 67 of file hs_service.h.

◆ circuit_retries

uint32_t circuit_retries

The amount of circuit creation we've made to this intro point. This is incremented every time we do a circuit relaunch on this intro point which is triggered when the circuit dies but the node is still in the consensus. After MAX_INTRO_POINT_CIRCUIT_RETRIES, we give up on it.

◆ enc_key_kp

Encryption keypair for the "ntor" type.

Definition at line 63 of file hs_service.h.

Referenced by hs_circ_handle_introduce2(), and service_intro_point_free_().

◆ introduce2_count

uint64_t introduce2_count

Amount of INTRODUCE2 cell accepted from this intro point.

Definition at line 77 of file hs_service.h.

Referenced by intro_point_should_expire().

◆ introduce2_max

uint64_t introduce2_max

Maximum number of INTRODUCE2 cell this intro point should accept.

Definition at line 80 of file hs_service.h.

Referenced by intro_point_should_expire().

◆ legacy_key

crypto_pk_t* legacy_key

Legacy key if that intro point doesn't support v3. This should be used if the base object legacy flag is set.

Definition at line 71 of file hs_service.h.

◆ legacy_key_digest

uint8_t legacy_key_digest[DIGEST_LEN]

Legacy key SHA1 public key digest. This should be used only if the base object legacy flag is set.

Definition at line 74 of file hs_service.h.

◆ onion_key

Onion key of the introduction point used to extend to it for the ntor handshake.

Definition at line 56 of file hs_service.h.

Referenced by setup_desc_intro_point().

◆ replay_cache

replaycache_t* replay_cache

Replay cache recording the encrypted part of an INTRODUCE2 cell that the circuit associated with this intro point has received. This is used to prevent replay attacks.

Definition at line 94 of file hs_service.h.

Referenced by hs_circ_handle_introduce2().

◆ support_intro2_dos_defense

unsigned int support_intro2_dos_defense

Support the INTRO2 DoS defense. If set, the DoS extension described by proposal 305 is sent.

Definition at line 98 of file hs_service.h.

Referenced by build_establish_intro_extensions().

◆ time_to_expire

time_t time_to_expire

The time at which this intro point should expire and stop being used.
