secure-password-utility

This NodeJS-password utility encourages the use of strong passwords in front-end applications.

To install this package, run npm i secure-password-utility.

When you call weakPasswordChecker you will get a boolean value.

Weak passwords like Passkey!@#41 or common words will also return false.

The weakPasswordChecker function will validate your input by ensuring that the password length is more than 11. It also confirms that the input contains a number and the combination of a special character,lowercase and uppercase. Finally, it rejects passwords containing known common words or fragments using a bundled wordlist (no network access required). You can extend the check with your own words by passing them as an optional third argument: weakPasswordChecker(password, length, ['mycompany', 'projectx']).

Once you display the conditions in your UI, this function will enforce the validation.

Generator functions (strongPasswordGenerator, createStrongPassword, productKeyGenerator, batchProductKeyGenerator) use cryptographically secure randomness and throw an InvalidInputError for unsupported arguments instead of returning "Invalid input" strings.

Quick Setup

Install the plugin using npm i secure-password-utility In your Node/Angular/React/Vue application: Install 'Types' plugin by running npm i -D @types/node Include "types": [ "node" ],in your tsconfig.json file and restart your IDE.

Development

• npm run build compiles src/ to dist/ (the published entry point).
• npm test runs the unit test suite (fully offline, no network required).
• npm run coverage produces an lcov coverage report.

Usage

*Validate password strength Syntax: securePasswordUtility.weakPasswordChecker('yourSamplePassword', lengthOfYourPassword); N.B. Ensure the length of the password you want to validate is at least 12-characters long.

*Generate a strong password Syntax: securePasswordUtility.createStrongPassword(lengthOfYourPassword); N.B. The password length must be more than 12.

*Generate a product key Syntax: securePasswordUtility.productKeyGenerator(lengthOfYourProductKey); N.B. The password length must be a multiple of 4 or 5 between 16 and 100 e.g. 16 or 25

const securePasswordUtility = require('secure-password-utility'); // Add this in your top-level class or file
