Overview

paspio — pasvorta entropio

A (naive) password entropy calculator.

Refrain from using this as a sole measure of password strength, it should be used in conjuction with other tools.

Usage

paspio can act as both a library and a command-line program.

If you're intending on using the program, run the following in your terminal:

# Pass one or more passwords to paspio to get their entropy
paspio "liuLe9ohjub8hu2ie"

If you're using it in your own program, add the following to your project's Cargo.toml and have a look at the documentation while you're at it.

paspio = "0.2"

Installation

crates.io

cargo install paspio

git clone https://aur.archlinux.org/paspio-git.git
cd paspio-git
makepkg -si

Building from source

git clone https://github.com/grtcdr/paspio
cd paspio
cargo build
# You should move it to your PATH now...

FAQ

How does this calculator calculate entropy?

Entropy = L * log2(R)

Where:

L is the length of the password.
R is the size of the pool of characters the password exists in.

Pool? What pool?

Pool	Elements	Pool size	Notes
Lowercase latin letters	[a-z]	26
Uppercase latin letters	[A-Z]	26
Digits	[0-9]	10
Symbols	`~!@#$%^&*()-=_+[{]}\|;' :",.<>/?	33	Whitespace is included
