[IPython-dev] Disabling Authentication for Kernels

[Andrew Gibiansky]

Thanks for the example.

Is the signature supposed to be in any way readable? I am getting something
like

\xf6\xd9hV\xea\xa0\xe1\x9cV\x9f"\xa5\x04\x8f\x87\x05\xd4=\xde\x04V4\xcc\x9eo\xcc/\x10\x92\x16I\x0f

Perhaps this is the issue?
