Can someone recommend a good resource to analyze entropy in a file as the author discussed?
- zeeboo 8y agoThe easy way: compress it with whatever you want (xz? gzip?) and compare the sizes. If it doesn't get significantly smaller, it's probably encrypted or already compressed.
- danmg 8y agobinwalk -E Will show a graph of the file offset vs shannon entropy.
- lcq2 8y agoread "A Mathematical Theory Of Communication" by Shannon himself, it's the only source you will ever need, it's available for free
