# For Developers {#developer}

Version 5 of this extension comes up with a lot of "microservices" that allows you to add your own
[security checks](https://docs.typo3.org/permalink/leuchtfeuer/secure-downloads:developer-securitychecks@14.1) and to generate your own [tokens](https://docs.typo3.org/permalink/leuchtfeuer/secure-downloads:developer-token@14.1). Older and deprecated
Hooks are now available as [PSR-14 Event](https://docs.typo3.org/permalink/leuchtfeuer/secure-downloads:developer-events@14.1) where you can listen to. In addition, a powerful
[API](https://docs.typo3.org/permalink/leuchtfeuer/secure-downloads:developer-securedlinks@14.1) allows you to generate secured links in your own extension.
