Learn Next.js mentions “encrypted closures” as an important security mechanism as part of Server Actions, where some of your Next.js app runs on the server instead of in client-side JavaScript.
I know what a closure is and I know what encryption is. However, I have no idea (and can’t find any resources about) what “encrypted closures” are. Does anyone know:
- How they work
- What attacks they prevent
- What situations they are most useful?
I searched google, bing, and ChatGPT for information but couldn’t find anything.
