LengthAnalyzer

password_strength::analyzer::length

Struct LengthAnalyzer

pub struct LengthAnalyzer;

Expand description

LengthAnalyzer is an analyzer that evaluates the strength of a password based on its length.

It assigns a score between 0.0 and 1.0, where:

Passwords shorter than 8 characters receive a score of 0.0.
Passwords with 16 or more characters receive a score of 1.0.
Passwords between 8 and 16 characters receive a score linearly interpolated between 0.0 and 1.0.

§Examples

use password_strength::analyzer;
use password_strength::analyzer::Analyzer;
use password_strength::analyzer::length::LengthAnalyzer;

let analyzer = LengthAnalyzer::default();

assert_eq!(analyzer.analyze("short"), 0.0);
assert_eq!(analyzer.analyze("verylongpassword"), 1.0);
assert_eq!(analyzer.analyze("mediumpass"), 0.25);
