eth-hash
The Ethereum hashing function, keccak256, sometimes (erroneously) called sha3
Note: the similarly named pyethash has a completely different use: it generates proofs of work.
This is a low-level library, intended to be used internally by other Ethereum tools.
If you're looking for a convenient hashing tool, check out
eth_utils.keccak()
which will be a little friendlier, and provide access to other helpful utilities.
Read the documentation.
Installation
python -m pip install "eth-hash[pycryptodome]"
>>> from eth_hash.auto import keccak
>>> keccak(b'')
b"\xc5\xd2F\x01\x86\xf7#<\x92~}\xb2\xdc\xc7\x03\xc0\xe5\x00\xb6S\xca\x82';{\xfa\xd8\x04]\x85\xa4p"
