Tor spec says Relay cell payloads consist of:
relay command
streamID
digest
length
data
Yet in another place it says Relay *EXTEND* cell payloads consist of:
address
port
onion skin
indentify fingerprint
Are EXTENDs somehow special & have different payloads than other Relay cells?
----
Also, why is address field of EXTEND hard wired to IPv4 only? What about
IPv6?
----
Some places talk about seeding a hash. I assume this means adding unique
stuff to a SHA1 hash?? Where are the details of 'seeding hashes' found?
THANKS!
