Simple hash-mining c library and its python binding.

## Requirements

-   `cmake` and things to build

-   non-old CPU for AVX2 instructions

    -   Check `flags` sections of your `/proc/cpuinfo`.

-   OpenMP (optional)

## How to Install

``` sh

$ pip install proofofwork

```

## How to Use

``` python

>>> import proofofwork

>>> import hashlib

>>> s = proofofwork.md5('00000000')

>>> s

b'erno8AAA'

>>> hashlib.md5(s).hexdigest()

'0000000057c4ca67d38e6826053824bd'

>>> s = proofofwork.sha1('000??????????????????????????????????000', text=b'sha1{????????}', alphabet=bytes(range(128, 256)))

>>> s

b'sha1{\xcb\xf0\xa4\x80\x80\x80\x80\xe0}'

>>> hashlib.sha1(s).hexdigest()

'00099d6917591c54f861032fd0d0071fbc647000'

```
