leekspin 2.1.1

An Onion Router descriptor generator

An Onion Router descriptor generator

Leekspin (á la the original internet masterpiece) is a small tool for generating mock Onion Router (OR) descriptors such as those used by relays, bridges, and Hidden Services (HS) within the Tor network in order to convey information about said relay, bridge, or Hidden Service to the Tor directory authorities, the bridge authority, Tor clients connecting to the network, and/or other relays within the network.

This tool is meant to be used to generate mock descriptors for testing or fuzzing other Tor libraries and programs, such as Stem, BridgeDB, and Tor. The keys, hash digests, and signatures generated within these mock descriptors are meant to be indistinguishable from those generated by real relays, bridges, and Hidden Services within the Tor network.

Installing

The very simplest way, if you use pip, would be to do:

$ pip install leekspin

Otherwise, the standard setuptools commands work just fine:

$ git clone https://git.torproject.org/user/isis/leekspin.git
$ cd leekspin
$ python setup.py install --record installed-files.txt

Running

Leekspin will install a script named… leekspin. To use it to generate twenty-three Bridge descriptors, do:

$ leekspin --bridge -n 23

And to generate forty-two Relay descriptors:

$ leekspin --relay -n 42

And, likewise, to generate ten hidden service descriptors, do:

$ leekspin --hidden-service -n 10

Commandline Flags

$ leekspin -h
usage: leekspin [-h] [[-v | -q] [--version] [-r | -b | -hs] [-n DESCRIPTORS]

Generate a signed set of network-status, extra-info, and server descriptor
documents for mock Tor relays or bridges.

Optional arguments:

-h, --help

show this help message and exit

-v, --verbose

print information to stdout

-q, --quiet

don’t print anything

--version

print leekspin version and exit

Descriptor types:

-r, --relay

generate Relay descriptors

-b, --bridge

generate Bridge descriptors

-hs, --hidden-service

generate Hidden Service rendezvous descriptors

Descriptor variations:

-xt, --without-tap

generate descriptors without TAP support, e.g. without RSA keys

-xn, --without-ntor

generate descriptors without ntor support, e.g. without Ed25519 keys

Required arguments:

-n DESCRIPTORS, --descriptors DESCRIPTORS

generate <n> sets of descriptors

Bugs

Should you decide to use this tool, and especially should you be so insane as to try hacking on it, you will likely find bugs. You may find bugs in Leekspin, BridgeDB, Stem, Tor’s specifications , and possibly even in Tor. Please, for math’s sake! Report them! The Tor developers will love you forever.
