TypeError with base64 when using JWS.verify_compact

[juanifioren]

Am having problems when running JWS().verify_compact(id_token, RSAKEYS):

Traceback (most recent call last):
  File "/Users/juanifioren/Projects/django-oidc-provider/oidc_provider/tests/test_token_endpoint.py", line 191, in test_idtoken_sign_validation

Am running Django tests.
I found a post. What could be causing the problem?.

Hi @rohe,

It breaks with pyjwkest==1.0.1 in all envs py2.7 py3.4 django1.7 django1.8.

Read here: http://stackoverflow.com/questions/2229827/django-urlsafe-base64-decoding-with-decryption

I sent you a pull request. https://github.com/rohe/pyjwkest/pull/31

Greetings.

[juanifioren]

My fault @rohe, instead of using decode in your function I can encode my parameter, so:

JWS().verify_compact(id_token.encode('utf-8'), RSAKEYS)

Will fix my problem, thanks anyways.
