Extract Entropies

Open n1073645 opened this issue 6 years ago • 1 comments

This is an operation that does the following:

  • Extracts anything with low entropy compared to the rest of the input data.
  • Extracts anything with high entropy compared to the rest of the input data.
  • Extract both low and high.
  • Extract anything in the English text range (3.5-5)
  • Allows you to put in your own range and extract any block that falls in that range.
  • Allows the user to choose what deviation algorithm to use (Mean absolute deviation or standard deviation)
  • Allows you to choose a block size and a block size range.
  • There is a button that can invert all of the criteria for the extractors.
  • Contained in this PR there is now an entropy library in the lib folder that all operations can make use of.

Hey! This pull request has gotten rather old and that's our fault. This project stopped being actively maintained for a while and it looks like your pull request has started to gather dust. Would you be able to update your branch to the latest version of CyberChef and we'll give it a review?

Hey, this PR has remained without updates for four weeks now. I'll close it now, but feel free to re-open if you find time to contribute! 😄
