Feb 7, 2020 · It's more for reverse engineering binaries of software that implements encryption of some type. Low entropy suggests a lack of encryption, while high entropy indicates possible encryption or compression. While its primary focus is firmware analysis, it supports a wide variety of file and data types. It'll find signatures in the binaries of these encryption methods, giving you a place to look when, for example, reverse engineering a file format that you suspect is encrypted in some way.
