# Ethereum Keyfile
A library for handling the encrypted keyfiles used to store ethereum private keys
> This library and repository was previously located at https://github.com/pipermerriam/ethereum-keyfile. It was transferred to the Ethereum foundation github in November 2017 and renamed to `eth-keyfile`. The PyPi package was also renamed from `ethereum-keyfile` to `eth-keyfile`.
## Installation
```sh
pip install eth-keyfile
```
## Development
```sh
pip install -e .[dev]
```
### Running the tests
You can run the tests with:
```sh
py.test tests
```
Or you can install `tox` to run the full test suite.
### Releasing
Pandoc is required for transforming the markdown README to the proper format to
render correctly on pypi.
For Debian-like systems:
```
apt install pandoc
```
Or on OSX:
```sh
brew install pandoc
```
To release a new version:
```sh
make release bump=$$VERSION_PART_TO_BUMP$$
```
#### How to bumpversion
The version format for this repo is `{major}.{minor}.{patch}` for stable, and
`{major}.{minor}.{patch}-{stage}.{devnum}` for unstable (`stage` can be alpha or beta).
To issue the next version in line, specify which part to bump,
like `make release bump=minor` or `make release bump=devnum`.
If you are in a beta version, `make release bump=stage` will switch to a stable.
To issue an unstable version when the current version is stable, specify the
new version explicitly, like `make release bump="--new-version 2.0.0-alpha.1 devnum"`
## Documentation
### `eth_keyfile.load_keyfile(path_or_file_obj) --> keyfile_json`
Takes either a filesystem path represented as a string or a file object and
returns the parsed keyfile json as a python dictionary.
```python
>>> from eth_keyfile import load_keyfile
>>> load_keyfile('path/to-my-keystore/keystore.json')
{
"crypto" : {
"cipher" : "aes-128-ctr",
"cipherparams" : {
"iv" : "6087dab2f9fdbbfaddc31a909735c1e6"
},
"ciphertext" : "5318b4d5bcd28de64ee5559e671353e16f075ecae9f99c7a79a38af5f869aa46",
"kdf" : "pbkdf2",
"kdfparams" : {
"c" : 262144,
"dklen" : 32,
"prf" : "hmac-sha256",
"salt" : "ae3cd4e7013836a3df6bd7241b12db061dbe2c6785853cce422d148a624ce0bd"
},
"mac" : "517ead924a9d0dc3124507e3393d175ce3ff7c1e96529c6c555ce9e51205e9b2"

"version" : 3
}
```
### `eth_keyfile.create_keyfile_json(private_key, password, kdf="pbkdf2", work_factor=None, salt_size=16) --> keyfile_json`
Takes the following parameters:
* `private_key`: A bytestring of length 32
* `password`: A bytestring which will be the password that can be used to decrypt the resulting keyfile.
* `kdf`: The key derivation function. Allowed values are `pbkdf2` and `scrypt`. By default, `pbkdf2` will be used.
* `work_factor`: The work factor which will be used for the given key derivation function. By default `1000000` will be used for `pbkdf2` and `262144` for `scrypt`.
* `salt_size`: Salt size in bytes.
Returns the keyfile json as a python dictionary.
```python
>>> private_key = b'\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01'
>>> create_keyfile_json(private_key, b'foo')
{
"address" : "1a642f0e3c3af545e7acbd38b07251b3990914f1",
"crypto" : {
"cipher" : "aes-128-ctr",
"cipherparams" : {
"iv" : "6087dab2f9fdbbfaddc31a909735c1e6"
},
"ciphertext" : "5318b4d5bcd28de64ee5559e671353e16f075ecae9f99c7a79a38af5f869aa46",

"version" : 3
}
```
### `eth_keyfile.decode_keyfile_json(keyfile_json, password) --> private_key`
Takes the keyfile json as a python dictionary and the password for the keyfile,
returning the decoded private key.
```python
>>> keyfile_json = {
... "crypto" : {
... "cipher" : "aes-128-ctr",
... "cipherparams" : {
... "iv" : "6087dab2f9fdbbfaddc31a909735c1e6"
... },
... "ciphertext" : "5318b4d5bcd28de64ee5559e671353e16f075ecae9f99c7a79a38af5f869aa46",
... "kdf" : "pbkdf2",
... "kdfparams" : {
... "c" : 262144,
... "dklen" : 32,
... "prf" : "hmac-sha256",
... "salt" : "ae3cd4e7013836a3df6bd7241b12db061dbe2c6785853cce422d148a624ce0bd"

... "mac" : "517ead924a9d0dc3124507e3393d175ce3ff7c1e96529c6c555ce9e51205e9b2"
... },
... "id" : "3198bc9c-6672-5ab3-d995-4942343ae5b6",
... "version" : 3
... }
>>> decode_keyfile_json(keyfile_json, b'foo')
b'\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01'
```
### `eth_keyfile.extract_key_from_keyfile(path_or_file_obj, password) --> private_key`
Takes a filesystem path represented by a string or a file object and the
password for the keyfile. Returns the private key as a bytestring.
```python
>>> extract_key_from_keyfile('path/to-my-keystore/keyfile.json', b'foo')
b'\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01'
