# Programming language support

Document Engine exposes a language-independent HTTP API, which means it **supports all languages and platforms**, including ASP.NET, PHP, Ruby, and Java.

Your backend must be able to generate valid [JSON Web Tokens (JWTs) for authentication](https://www.nutrient.io/guides/document-engine/viewer/client-authentication.md). Document Engine uses the standardized JWT format. The benefit of this format is that it has [countless implementations in different programming](http://jwt.io) languages.
