![]() $generator = new HumanPasswordGenerator() Human Password Generator Usage use Hackzilla\ PasswordGenerator\ Generator\ HumanPasswordGenerator The segment separator will be remove from the possible characters. If you can think of a better name for this password generator then let me know. $password = $generator-> generatePasswords( 10) $generator = new HybridPasswordGenerator() $password = $generator-> generatePasswords( 10) Hybrid Password Generator Usage use Hackzilla\ PasswordGenerator\ Generator\ HybridPasswordGenerator use Hackzilla\ PasswordGenerator\ Generator\ ComputerPasswordGenerator If you want to generate 10 passwords that are 12 characters long. $password = $generator-> generatePassword() More Passwords Usage > setOptionValue( ComputerPasswordGenerator:: OPTION_SYMBOLS, false) > setOptionValue( ComputerPasswordGenerator:: OPTION_NUMBERS, true) > setOptionValue( ComputerPasswordGenerator:: OPTION_LOWER_CASE, true) > setOptionValue( ComputerPasswordGenerator:: OPTION_UPPER_CASE, true) $generator = new ComputerPasswordGenerator() Simple Usage use Hackzilla\ PasswordGenerator\ Generator\ ComputerPasswordGenerator Now tell composer to download the library by running the command: $ composer require hackzilla/password-generatorĬomposer will add the library to your composer.json file and install it into your project's vendor/hackzilla directory. This function parses command line options and arguments and returns an associative array of the options and their values.Simple library for generating random passwords. To set up the command line interface, we'll use PHP's built-in getopt() function. I'm going to name mine, cli-passwd-gen.php. Set Up The Command Line Interfaceįirst, create a PHP file for this program. In a few lines of code, we will create a simple, but effective password generator that can be used to create strong and secure passwords on the fly. This will help us select random characters for the password string.Random_int() - Generates a cryptographically random integer. We will use this to validate user input.Pregmatch() - Finds a match for a specified regular expression. We will use this when handling input validation errors.This allows us to determine the optional arguments that the user has selected.Įxit() - Terminates the program and outputs a message to the screen.Strpos() - Finds the position of the first occurrence of a substring in a string. This will help us verify that the user has set the required options.Isset() - Determines whether a variable has been set or not. ![]() This will allow us to take in user input to customize the password.Getopt() - Parses command-line options and arguments into an array. We will also need to use the following built-in PHP functions: l, -length - Integer value denoting the number of characters the user wants to include in their password. Which represent: lowercase, uppercase, numbers, and/or special (for special characters). There are only four valid values for this argument: ' l', 'u', 'n', 's'.t, -types - Types of characters the user wants to include in the password. When executing the command, the user will need to specify values for the following required arguments: The generated password should output to the command line at the completion The characters in the password should be random ![]() Program RequirementsĬapability to specify the length of the passwordĬapability to specify character types (lowercase, uppercase, numbers, and/or special characters) ![]() Before getting started, we should consider the program requirements for cli-passwd-gen. The basic concept of cli-passwd-gen is to create a random string of characters and then print the resulting string to the screen. And we are going to call this tool, cli-passwd-gen. So, we are going to walk through the process of building a simple PHP CLI tool for generating random passwords. Generating strong, random passwords is an important security practice for anyone living in the 21st century, but especially for devs. ![]()
