[tor-commits] [torspec/master] Move section 4.5 to the appendix.
commit a8f52765f394a6e23866ba28b4781fa530f03114
Author: Karsten Loesing <karsten.loesing@xxxxxxx>

Move section 4.5 to the appendix.
"General-use HTTP URLs" is not an operation but a reference, and
references belong in the appendix.
This commit does not yet repair section numbering or references.

-4.5. General-use HTTP URLs
-
- "Fingerprints" in these URLs are base16-encoded SHA1 hashes.
-
- The most recent v3 consensus should be available at:
- http://<hostname>/tor/status-vote/current/consensus.z
-
- Starting with Tor version 0.2.1.1-alpha is also available at:
- http://<hostname>/tor/status-vote/current/consensus/<F1>+<F2>+<F3>.z
-
- (NOTE: Due to squid proxy url limitations at most 96 fingerprints can be
- retrieved in a single request.)
-
- Where F1, F2, etc. are authority identity fingerprints the client trusts.
- Servers will only return a consensus if more than half of the requested
- authorities have signed the document, otherwise a 404 error will be sent
- back. The fingerprints can be shortened to a length of any multiple of
- two, using only the leftmost part of the encoded fingerprint. Tor uses
- 3 bytes (6 hex characters) of the fingerprint.
-
- Clients SHOULD sort the fingerprints in ascending order. Server MUST
- accept any order.
-
- Clients SHOULD use this format when requesting consensus documents from
- directory authority servers and from caches running a version of Tor
- that is known to support this URL format.
-
- A concatenated set of all the current key certificates should be available
- at:
- http://<hostname>/tor/keys/all.z
-
- The key certificate for this server (if it is an authority) should be
- available at:
- http://<hostname>/tor/keys/authority.z
-
- The key certificate for an authority whose authority identity fingerprint
- is <F> should be available at:
- http://<hostname>/tor/keys/fp/<F>.z
-
- The key certificate whose signing key fingerprint is <F> should be
- available at:
- http://<hostname>/tor/keys/sk/<F>.z
-
- The key certificate whose identity key fingerprint is <F> and whose signing
- key fingerprint is <S> should be available at:
-
- http://<hostname>/tor/keys/fp-sk/<F>-<S>.z
-
- (As usual, clients may request multiple certificates using:
- http://<hostname>/tor/keys/fp-sk/<F1>-<S1>+<F2>-<S2>.z )
- [The above fp-sk format was not supported before Tor 0.2.1.9-alpha.]
-
- The most recent descriptor for a server whose identity key has a
- fingerprint of <F> should be available at:
- http://<hostname>/tor/server/fp/<F>.z
-
- The most recent descriptors for servers with identity fingerprints
- <F1>,<F2>,<F3> should be available at:
- http://<hostname>/tor/server/fp/<F1>+<F2>+<F3>.z
-
- (NOTE: Due to squid proxy url limitations at most 96 fingerprints can be
- retrieved in a single request.
-
- Implementations SHOULD NOT download descriptors by identity key
- fingerprint. This allows a corrupted server (in collusion with a cache) to
- provide a unique descriptor to a client, and thereby partition that client
- from the rest of the network.)
-
- The server descriptor with (descriptor) digest <D> (in hex) should be
- available at:
- http://<hostname>/tor/server/d/<D>.z

- The most recent descriptors with digests <D1>,<D2>,<D3> should be
- available at:
- http://<hostname>/tor/server/d/<D1>+<D2>+<D3>.z
-
- The most recent descriptor for this server should be at:
- http://<hostname>/tor/server/authority.z
- [Nothing in the Tor protocol uses this resource yet, but it is useful
- for debugging purposes. Also, the official Tor implementations
- (starting at 0.1.1.x) use this resource to test whether a server's
- own DirPort is reachable.]
-
- A concatenated set of the most recent descriptors for all known servers
- should be available at:
- http://<hostname>/tor/server/all.z
-
- Extra-info documents are available at the URLS
- http://<hostname>/tor/extra/d/...
- http://<hostname>/tor/extra/fp/...
- http://<hostname>/tor/extra/all[.z]
- http://<hostname>/tor/extra/authority[.z]
- (As for /tor/server/ URLs: supports fetching extra-info
- documents by their digest, by the fingerprint of their servers,
- or all at once. When serving by fingerprint, we serve the
- extra-info that corresponds to the descriptor we would serve by
- that fingerprint. Only directory authorities of version
- 0.2.0.1-alpha or later are guaranteed to support the first
- three classes of URLs. Caches may support them, and MUST
- support them if they have advertised "caches-extra-info".)
-
- For debugging, directories SHOULD expose non-compressed objects at URLs like
- the above, but without the final ".z".
- Clients MUST handle compressed concatenated information in two forms:
- - A concatenated list of zlib-compressed objects.
- - A zlib-compressed concatenated list of objects.
- Directory servers MAY generate either format: the former requires less
- CPU, but the latter requires less bandwidth.
-
- Clients SHOULD use upper case letters (A-F) when base16-encoding
- fingerprints. Servers MUST accept both upper and lower case fingerprints
- in requests.
