I have the same problem as in 'How to apply pyethrecover.py on v3 .json/transfor v3 .json to .v1' referenced here, but in trying the answer's code, I am finding that the Crypto package is not being recognized.
I installed 'Crypto' from within PyCharm and it reports installing (i.e. notification and event logs), but the IDE still shows this it as an 'Unresolved Reference' and produces the error below while running utils.py:
try: from Crypto.Hash import keccak sha3_256 = lambda x: keccak.new(digest_bits=256, data=x).digest() except ImportError: import sha3 as _sha3 sha3_256 = lambda x: _sha3.keccak_256(x).digest()
AttributeError: 'module' object has no attribute 'keccak_256'
What am I missing? I am using Python 2.7.10 in PyCharm. Thanks.
