hi everyone

i am a computer science student and am currently trying to implement a
razor2-client in java. since there is almost no documentation i'm trying
to reverse engineer the whole thing. there are two questions i can't
answer by reading the source code:

(1) is it necessary that every client and every catalogue server choose
the exactly same parts of a message for hashing? the fact that the server
supplies a seed for the random number generator leads me to this
assumption.

(2) if (1) is true, why do you use perls random number generator (which
could be different on every client) for this purpose, instead of including
an own one in your source code, making razor independent from the rng of
the system it is running on. (as a matter of fact, you get different
random numbers if you run razor on linux vs if you run it on windows)

(3) what are signatures v5 and higher that are used by spamnet? are they
documented anywhere or are they kind of "secret" since they only appear in
spamnet, not in razor?

thanks for any help.

Simon
