Lightbulb DataSmoke

Entropy Calculation Files (DataSmoke By Bulat Ziganshin)

https://github.com/Bulat-Ziganshin/DataSmoke







Provides the following results on each scanned file.

1) Byte entropy

2) Word entropy

3) Order-1 byte entropy

4) DWord hash entropy

5) DWord coverage

6) 2-pass DWord coverage

7) 2-pass QWord coverage

Possibility of scanning the full directory, with real-time calculation of the average percentage for each result.

Calculation of the real-time percentage average of all results, with estimated final size.

Thanks to Gozarck for the idea.

Upsss. datasmoke.exe crash.

PD:I would like the application create a list of files which have a specific entropy percentage.
Example:
Sort files with 90% of entropy and create a list of those files.
Result in prompt:
data_1.pkg 91% entropy
data_2.pkg 31% entropy
data_3.pkg 11% entropy
data_4.pkg 92% entropy
data_5.pkg 94% entropy
Result in list.txt:
D:\Game\data\data_1.pkg
D:\Game\data\data_4.pkg
D:\Game\data\data_5.pkg

Buf 4 mb default crash

Smoke.exe works fine.
I use smoke since 2015. It's a great tool.
