I was wondering which language is best to build a .onion website (PHP, Python, ...). Which language is more secure and which frameworks are more secure?
Is it a good idea to use CSS (Cascading Style Sheets)? Most .onion websites I've seen are written in HTML
Is true that HTTP server language and web framework has at one point had a vulnerability that exposes configuration or environment variables? If yes, how does that happen and how to avoid this problem?
