Wrong cffi version assertion

[wikier]

With a regular installation (pip install pyjwkest) I get a cffi assertion error:

>>> import jwkest.jwk
Traceback (most recent call last):

  File "/home/wikier/.local/lib/python3.5/site-packages/jwkest/jwk.py", line 11, in <module>

    ffi = FFI()

    "version mismatch, %s != %s" % (backend.__version__, __version__)
AssertionError: version mismatch, 1.7.0 != 1.8.3

Which I manage to fix by manually forcing the version:

pip install cffi==1.7.0

So that needs to be declared in the package dependencies.

This is not really a pyjwkest issue, it’s pycryptodome that needs that version of cffi.

OK, thanks.
