| #define AUTHTYPE_ED25519_SHA256_RFC5705 3 |
| #define AUTHTYPE_RSA_SHA256_RFC5705 2 |
As AUTHTYPE_RSA_SHA256_TLSSECRET, but instead of using the negotiated TLS secrets, uses exported keying material from the TLS session as described in RFC 5705.
Not used by today's tors, since everything that supports this also supports ED25519_SHA256_5705, which is better.
| #define AUTHTYPE_RSA_SHA256_TLSSECRET 1 |
The first supported type of AUTHENTICATE cell. It contains a bunch of structures signed with an RSA1024 key. The signed structures include a HMAC using negotiated TLS secrets, and a digest of all cells sent or received before the AUTHENTICATE cell (including the random server-generated AUTH_CHALLENGE cell).

| typedef uint32_t circid_t |
| typedef enum path_state_t path_state_t |
| typedef uint16_t streamid_t |
Enumerates possible origins of a client-side address mapping.
| enum cell_direction_t |
| enum consensus_flavor_t |
| enum dirinfo_type_t |
Bitfield enum type listing types of information that directory authorities can be authoritative about, and that directory caches may or may not cache.
Note that the granularity here is based on authority granularity and on cache capabilities. Thus, one particular bit may correspond in practice to a few types of directory info, so long as every authority that pronounces officially about one of the types prounounces officially about all of them, and so long as every cache that caches one of them caches all of them.
| enum download_schedule_t |
Enumeration: is the download schedule for downloading from an authority, or from any available directory mirror? During bootstrap, "any" means a fallback (or an authority, if there are no fallbacks). When we have a valid consensus, "any" means any directory server.
| enum rend_auth_type_t |
| enum saved_location_t |
Enum used to remember where a signed_descriptor_t is stored and how to manage the memory for signed_descriptor_body.
