HashedPassword Usage

• To hash a password, use the hashedPassword function provided in the package.

const password = 'securePassword';

const hashPassword = async () => {
    const hashed = await hashedPassword(password);
    return hashed;
};

ValidatePassword Usage

• To validate a password against a hashed password, use the validatePassword function provided in the package.

import { validatePassword, hashedPassword } from '@chetanc_2002/common';

const checkPassword = async () => {
    const password = 'securePassword';
    const hashed = await hashedPassword(password); // Assume hashed is a stored hashed password
    const isValid = await validatePassword(password, hashed);
    
    if (isValid) {
        console.log('Password is valid');
    } else {
        console.log('Password is invalid');
    }
};
