Fuzzy bit library

Project Description

Fuzzybit is a library for determining possible values of bits in integers based on observed concrete values.

Install

To install fuzzybit (after downloading):

python setup.py install

To install fuzzybit with pip:

pip install fuzzybit

Using fuzzybit

Here is an example of tracking a single bit using the FuzzyBit class:

>>> import fuzzybit
>>> b = fuzzybit.FuzzyBit()
>>> b.get_value()
'?'

>>> b.observe_value('0')
>>> b.get_value()
'0'
>>> b.get_entropy()
0

>>> b.observe_value('0')
>>> b.get_value()
'0'
>>> b.get_entropy()
0

>>> b.observe_value('1')
>>> b.get_value()
'*'
>>> b.get_entropy()
1

Here is an example of tracking an integer using the FuzzyInt class:

>>> import fuzzybit
>>> x = fuzzybit.FuzzyInt(16)  # Create 16 bit integer
>>> x.get_value()
'????????????????'

>>> x.observe_value(0x0ff0)
>>> x.get_value()
'0000111111110000'
>>> x.get_entropy()
0

>>> x.observe_value(0x0000)
>>> x.get_value()
'0000********0000'
>>> x.get_entropy()
8

>>> x.observe_value(0x0dd1)
>>> x.get_value()
'0000********000*'
>>> x.get_entropy()
9
