validate-password

#JavaScript Password validation for the client and the server

Enforce stronger passwords for users by checking for uppercase/lowercase letters, numbers, and special characters.

You can also check passwords for certain strings. This is ideal for preventing users from entering their name or email in the password. Or, you can search the password for common words, to further encourage the user to pick a strong password.

##Installation Install via NPM:

npm install validate-password

##Usage

This can be used as a stand alone package:

<script src="node_modules/validate-password/dist/validate-password.min.js"></script>

or as a CommonJS module:

var ValidatePassword = require('validate-password');

Validate Password will accept two arguments - first, the password as a string:

var passwordData = ValidatePassword('aaaaa');

console.log(passwordData.isValid); // false
console.log(passwordData.validationMessage); // 'The password must contain at least one uppercase letter'

And, optionally, an array of strings that are not allowed to be in the password:

var checkPasswordForName = ValidatePassword('cat123aaBa$%^#$%#$%', ['cat123']);

console.log(passwordData.isValid); // false
console.log(passwordData.validationMessage); // 'The password cannot contain cat123'
