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

$ pip install proofofwork

How to Use

>>> 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'
