README

An absurdly simple package for generating and validating random requirement-based passwords for PHP.

Copyright (C) 2014 Brandon Fenning

Requirements

Compatible with PHP 5.3+

Installation

Add innoscience/passwordly to the composer.json file:

"require": {
    "innoscience/passwordly": "dev-master"
}

After this, run composer update

Usage

Passwordly is namespaced to innoscience/passwordly/passwordly, at the top of your file you'll want to use:

use Innoscience\Passwordly\Passwordly;

Creating passwords

When creating passwords, Passwordly first checks what the character requirements are. Any difference is made up with the addition of randomly cased alphanumeric characters.

#####Basic: generate random 8 character password, no symbols $password = Password::can()->generate(8);

#####Password with 1 - 3 symbols and 8 - 16 characters in length $password = Password::can()->hasSymbols(1,3)->generate(8, 16);

#####Password with at least 1 uppercase, lowercase and numeric character and 8 characters in length $password = Password::can()->hasLower(1)->hasNumbers(1)->hasUpper(1)->generate(8);

Checking password

#####Check that password has at least 1 number and upper case letter and is at least 8 characters in length $isOk = Password::can()->hasNumbers(1)->hasUpper(1)->hasLength(8)->check($password);

#####Check that password has no more than 1 to 3 numbers, 1 symbol and upper case letter and is at least 8 but not more than 16 characters in length $isOk = Password::can()->hasNumbers(1,3)->hasUpper(1)->hasSymbols(1)->hasLength(8,16)->strict()->check($password); When checking passwords, Passwordly does not use the maximum argument unless the ->strict() method is invoked.

#####Check password and get errors $passwordCheck = new Passwordly(); $isOk = $passwordCheck->hasNumbers(1)->hasUpper(1)->check($password); $errors = $passwordCheck->errors(); // # Returns array with each failed requirement

Details

Instantiating

Passwordly can be instantiated either via the Passwordly::can() static constructor or simply by calling new Passwordly. Reading the error messages requires access to the Passwordly instance, so chaining calls off of Passwordly::can() is not recommended for those use-cases.

Chainable Methods

• hasLower($min, $max = null) : The min/max number of lower-case characters that can be in a password.
• hasUpper($min, $max = null) : The min/max number of upper-case characters that can be in a password.
• hasNumbers($min, $max = null) : The min/max number of numeric characters that can be in a password.
• hasSymbols($min, $max = null) : The min/max number of non-alphanumeric characters that can be in a password.
• hasSpaces($min, $max = null) : The min/max number of spaces that can be in a password.
• hasLength($min, $max = null) : The min/max length of the password.
• strict() : Tells check() to also enforce the $max argument for all chainable methods

Final Methods

• generate($min, $max = null) : Generate a password of $min/$max size from the set requirements, returns a string
• check($password) : Check the password against the set requirements, returns true or false

Other Methods

• errors() : Returns an array of errors resulting from a ->check()

Utility Methods

These utility methods affect all instances of Passwordly when used.

• Passwordly::setLowerPool($characterPool) : Override the lower-case character pool
• Passwordly::setUpperPool($characterPool) : Override the upper-case character pool
• Passwordly::setNumberPool($characterPool) : Override the numeric character pool
• Passwordly::setSymbolPool($characterPool) : Override the symbol character pool
• Passwordly::getLowerPool() : Get the lower-case character pool
• Passwordly::getUpperPool() : Get the upper-case character pool
• Passwordly::getNumberPool() : Get the numeric character pool
• Passwordly::getSymbolPool() : Get the symbol character pool
• Passwordly::setDisableOpenssl($bool) : Passwordly uses the openssl_random_pseudo_bytes() function in php to generate random strings, if this is unavailable use this method and set it to TRUE to use a built-in alternative function.

Tests

Passwordly is fully unit tested. Tests are located in the tests directory of the Passwordly package and can be run with phpunit in the package's base directory.
