If key is bytes, encode works, decode fails

[friedcell]

>>> key = b'key'
>>> token = jwt.encode({'key': 'value'}, key, algorithm='HS256')
>>> jwt.decode(token, key, algorithms=['HS256'])
Traceback (most recent call last):
 File "<stdin>", line 1, in <module>

 if 'keys' in key:
TypeError: a bytes-like object is required, not 'str'

I think either both should work or both should fail.

I think this is fixed in #139.

I'm still getting this error. How do I fix this please? I can encode but the error happens when decoding.

Unfortunately i'm seeing the same thing. Here's my output from ipython ( Python 3.7.4 ) using release 3.1.0:
