Remailer Specs

-----BEGIN PGP SIGNED MESSAGE-----

        Since I have begun the project of writing the Remailer for the Mac,
I suddenly realized that I do not know exactly what is expected of it, and
therefore would like some pointers to the specs of a remailer (I have seen
references to padding and splitting but do not know what this is nor how to
implement it.)
TIA,

Well, you could look at some existing code.  My remailer is written in C,
with most of the unix-specific stuff being done by shell scripts, so
you should be able to compile some of the C code on the Mac (if you're
planning to write your remailer in C).

Look in:

ftp myriad.pc.cc.cmu.edu /pub/remailer
ftp cs.cmu.edu /afs/andrew.cmu.edu/usr12/mg5n/public/remailer

	I've started work on a formal remailer standards document that 
describes just how a Cypherpunk Type I remailer should process messages, 
with full header descriptions, etc. After I've checked it against the 
behaviors of all the various Cypherpunk remailer packages (Ghio vs Eric 
Hollander vs Sameer vs Mixmaster in compatibility mode vs whatever else), 
I'll post it here for comments.

Cypherpunk Type I?  Ok, what are the other types?  Should there be a
type specification like there is for RAID, or the Body Armor Threat
levels?

I would like to try my hand at writing a remailer, but I would like to
see standards, and level/type specifications.

E.g. The body armor threat levels are I - VI
VI is able to physically stop a 50 BMG round, i.e. prevent
penetration.  The wearer of the armor would likely die from the shock,
but would not be penetrated.  Level II includes all the abilites of
level I and then some, III = II + some more, etc until VI which is
all of the abilities in body armor.

I believe that RAID levels are 1-5, and I seem to remember that it is
graduated like the body armor threat levels, so that 2=1 + some stuff,
4=3 + some stuff, etc.

Should we come up with a similar type of graduated system, and specs
for each, with some kind of negotiation between remailers, so that they
can determine what levels to use to communicate with various
remailers?

Then we could talk in terms of type 6, for example, having all the
abilities of levels 1-5 and then some.

	Currently? Only Mixmaster AKA Cypherpunk Type II. This is part of 
why an official standards document is needed. My specs will include the 
start of an `official' type specification.

	Not a bad idea. I'll see what I can do.
