Is sha3-256 hash type unsupported by hashlib.pbkdf2_hmac?

Hi,

I tried to run py.test for test_client.py, 7 passed and only "test_transfer_coin()" failed. Anything I did wrong?

sha3-256 is noly optional in python3.7. If the system has openssl 1.1.0 above, seems there are sha3-* in python. May be you can update openssl and try again.

@yuan-xy Thank you very much for pointing out the direction. I tried on the latest Ubuntu (19.04)，all tests passed nicely.
