entropy — a minimal GNU-like tool for calculating entropy of files

Because how isn't there already one (in my favourite package manager)?

Installation (from source)

Prerequisites:

• An up-to-date Rust toolchain (2024 edition).

Installation steps:

1. Review the source code and dependencies for backdoors, malware and zero-day exploits.
2. Clone the repo.
3. Run cargo install --path . to install entropy locally for the current user.
4. ???
5. Profit!

Usage

See entropy --help.

Possible future features

• -r option to recursive traverse directories
• --algorithm option to specify other algorithms besides Shannon's entropy
• --pretty-print option to print a nice table with the results and explanations
