Okay, and now the python version does creation as well, though I haven't
checked if the C version can decode it:
$ ./test/test_onion 3 | python test/test_onion.py
Message to 0
Message to 1
Message to 2
done
$ python test/test_onion.py generate 3 | python test/test_onion.py
Howzit 0...
Howzit 1...
Howzit 2...
done
$ wc test/test_onion.{c,py} -l
684 test/test_onion.c
329 test/test_onion.py
(though about 1/3 of the python lines are just implementing "determine
y given x" and "ecdh with y as well as x", bleh. It also doesn't have
the "export-friendly encryption" mode implemented ;)
