        "description": "Ethereum Keyfile\n================\n\nA library for handling the encrypted keyfiles used to store ethereum\nprivate keys\n\n    This library and repository was previously located at\n    https://github.com/pipermerriam/ethereum-keyfile. It was transferred\n    to the Ethereum foundation github in November 2017 and renamed to\n    ``eth-keyfile``. The PyPi package was also renamed from\n    ``ethereum-keyfile`` to \\`eth-keyfile.\n\nInstallation\n------------\n\n.. code:: sh\n\n    pip install eth-keyfile\n\nDevelopment\n-----------\n\n.. code:: sh\n\n    pip install -e . -r requirements-dev.txt\n\nRunning the tests\n~~~~~~~~~~~~~~~~~\n\nYou can run the tests with:\n\n.. code:: sh\n\n    py.test tests\n\nOr you can install ``tox`` to run the full test suite.\n\nReleasing\n~~~~~~~~~\n\nPandoc is required for transforming the markdown README to the proper\nformat to render correctly on pypi.\n\nFor Debian-like systems:\n\n::\n\n    apt install pandoc\n\nOr on OSX:\n\n.. code:: sh\n\n    brew install pandoc\n\nTo release a new version:\n\n.. code:: sh\n\n    make release bump=$$VERSION_PART_TO_BUMP$$\n\nHow to bumpversion\n^^^^^^^^^^^^^^^^^^\n\nThe version format for this repo is ``{major}.{minor}.{patch}`` for\nstable, and ``{major}.{minor}.{patch}-{stage}.{devnum}`` for unstable\n(``stage`` can be alpha or beta).\n\nTo issue the next version in line, specify which part to bump, like\n``make release bump=minor`` or ``make release bump=devnum``.\n\nIf you are in a beta version, ``make release bump=stage`` will switch to\na stable.\n\nTo issue an unstable version when the current version is stable, specify\nthe new version explicitly, like\n``make release bump=\"--new-version 2.0.0-alpha.1 devnum\"``\n\nDocumentation\n-------------\n\n``eth_keyfile.load_keyfile(path_or_file_obj) --> keyfile_json``\n~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\n\nTakes either a filesystem path represented as a string or a file object\nand returns the parsed keyfile json as a python dictionary.\n\n.. code:: python\n\n    >>> from eth_keyfile import load_keyfile\n    >>> load_keyfile('path/to-my-keystore/keystore.json')\n    {\n        \"crypto\" : {\n            \"cipher\" : \"aes-128-ctr\",\n            \"cipherparams\" : {\n                \"iv\" : \"6087dab2f9fdbbfaddc31a909735c1e6\"\n            },\n            \"ciphertext\" : \"5318b4d5bcd28de64ee5559e671353e16f075ecae9f99c7a79a38af5f869aa46\",\n            \"kdf\" : \"pbkdf2\",\n            \"kdfparams\" : {\n                \"c\" : 262144,\n                \"dklen\" : 32,\n                \"prf\" : \"hmac-sha256\",\n                \"salt\" : \"ae3cd4e7013836a3df6bd7241b12db061dbe2c6785853cce422d148a624ce0bd\"\n            },\n            \"mac\" : \"517ead924a9d0dc3124507e3393d175ce3ff7c1e96529c6c555ce9e51205e9b2\"\n        },\n        \"id\" : \"3198bc9c-6672-5ab3-d995-4942343ae5b6\",\n        \"version\" : 3\n    }\n\n``eth_keyfile.create_keyfile_json(private_key, password, kdf=\"pbkdf2\", work_factor=None) --> keyfile_json``\n~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\n\nTakes the following parameters:\n\n-  ``private_key``: A bytestring of length 32\n-  ``password``: A bytestring which will be the password that can be\n   used to decrypt the resulting keyfile.\n-  ``kdf``: The key derivation function. Allowed values are ``pbkdf2``\n   and ``scrypt``. By default, ``pbkdf2`` will be used.\n-  ``work_factor``: The work factor which will be used for the given key\n   derivation function.
