If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

Informations about the package randomstringgenerator

Random String Generator

Generator\RandomStringGenerator generates cryptographically strong random strings based on a supplied alphabet of characters (such as alphanumeric characters). This is perfect for generating API keys within a set of allowed characters. It can also be used to generate strong passwords.

The class relies on the openssl_pseudo_random_bytes() function to generate the cryptographically strong random numbers for use in building the random strings.

Usage

To generate a 16-character string using the default 62-character alphanumeric alphabet, the usage is as simple as the following:

To use a different alphabet, such as uppercase hexadecimal characters, and to generate a random string of a different length, these parameters can be passed to the class as follows:

$generator = new RandomStringGenerator(RandomStringGenerator::ALPHABET_HEX_UPPER);
$key = $generator->generate(8);
// string(8) "CF70D24E"

A custom alphabet can be provided in the form of an input string of characters, such as:

$generator = new RandomStringGenerator('abc123');
$key = $generator->generate();
// string(16) "cb2c2a33c2c3a23b"

This is then converted to an array of characters internally. This array can be retrieved using the $generator->alphabet() function with no argument.
