passay-rs

passay-rs is a Rust library that provides password validation rules, inspired by the original Java library passay. It allows developers to enforce complex password policies such as minimum length, character composition, and exclusion of common words.

Features

• Validate passwords against a set of rules
• Support for various rule types such as:
  • Minimum and maximum length
  • Character composition (uppercase, lowercase, digits, special characters)
  • Exclusion of common words
  • Check for username or password reuse
  • Whitespace detection
  • Source reference matching
• Customizable rule behavior (e.g., case sensitivity, backwards matching)
• Extensible architecture to support additional rules and languages

Usage

To use passay-rs, add it to your Cargo.toml:

[dependencies]
passay-rs = "0.1.0"

Then, create and configure your password validation rules:

use passay_rs::rule::PasswordData;
use passay_rs::rule::Rule;
use passay_rs::rule::length::LengthRule;

fn main() {
    let rule = LengthRule::new(8, 20);
    let password_data = PasswordData::with_password("SecureP@ssw0rd".to_string());
    let result = rule.validate(&password_data);
    assert!(result.valid());
}
