Calculate the information entropy of some text
You can install entropy either by using Cargo, or by downloading a binary from the Releases page.
Run this in your shell:
sh
$ cargo install entropia
See the Releases page.
Entropy takes no arguments. It captures text on stdin and reports the information entropy of that text. For example:
``` $ cat file | entropy 2362.4587346565673
$ secret token | entropy 138.9089067264194
$ echo "Hello world" | entropy 69.68825906469124
$ entropy Hello world 69.68825906469124 ```
