Laravel Random Keys with Keygen
Jan 27, 2017 @ 12:44:13

On the Scotch.io site they've posted a new Laravel-related tutorial covering the use of the keygen package to generate random keys via four generator types. These keys can be used for just about anything in your application and can be customized to fit your length and complexity requirements. One thing to note, however, is that the strings it generates are random but should not be considered strong enough to use for actual encryption purposes.

When developing applications, it is usually common to see randomness come into play - and as a result, many programming languages have built-in random generation mechanisms.

[...] When your application is required to generate very simple random character sequences like those enumerated above, then the Keygen package is a good option to go for. Keygen is a PHP package for generating simple random character sequences of any desired length and it ships with four generators, namely: numeric, alphanumeric, token and bytes.

For their example they chose to create a simple REST API service that allows for user creation, viewing users and generating a random (temporary) password using the Keygen package. They start by helping you get the package installed (via Composer) and adding an alias to your Laravel config for "Keygen" to make it easier to access. They then create the user model and add in a "setEmailAttribute" method to verify the email value submitted (for format and uniqueness). Next up is the route definition for the "user" endpoints, creation of the API controller and implementing the Keygen tool to create a random eight digit code for the user. They also include a few strategies to ensure the code generated (and the resulting hash) is unique across all users. The reminder of the post shows the full user creation, and implementing the remaining methods required to view the user's details.
