4. The rendezvous protocol
XXXX write me
A. Hidden servers use SHA-1 to establish introduction points on relays,
and relays use SHA-1 to check incoming introduction point
establishment requests.
B. Hidden servers use SHA-1 in multiple places when generating hidden
service descriptors.
C. Hidden servers performing basic-type client authorization for their
services use SHA-1 when encrypting introduction points contained in
hidden service descriptors.
D. Hidden service directories use SHA-1 to check whether a given hidden
service descriptor may be published under a given descriptor
identifier or not.
E. Hidden servers use SHA-1 to derive .onion addresses of their
services.
F. Clients use SHA-1 to generate the current hidden service descriptor
identifiers for a given .onion address.
G. Hidden servers use SHA-1 to remember digests of the first parts of
Diffie-Hellman handshakes contained in introduction requests in order
to detect replays.
H. Hidden servers use SHA-1 during the Diffie-Hellman key exchange with
a connecting client.
5. The bridge protocol
