triplesec CLI executable fails: sha3_512 not in hashlib

[genos]

After installing via pip3 [Python 3.5.2 on OS X 10.11.6], I'm unable to use the triplesec executable due to the following error:

$ triplesec -k 'key' enc 'message'                                                                                                                                                                                                                                                                                                                                  <<<

Install pysha3 and make sure this piece of code is in "/usr/local/lib/python3.5/site-packages/triplesec/utils.py" after the import statements:

if sys.version_info < (3, 6):
    import sha3

I'm willing to hack on the code myself, but shouldn't this change be in the code, not in my local copy?

I think the fix for this is in master but not yes released to PyPI. I'll confirm that and then see about getting the PyPI package updated.

[oconnor663]

Ok, v0.4 is up, and it looks like it works for me. Let me know if you see this again.

Great, thanks very much!
