file_security

Middleware for securing file uploads.

Supports:

• Max file sizes
• Max # of uploaded files
• Restrict to certain extensions
• Restrict to certain content types
• Virus scan uploaded files via VirusTotal*

Your file upload API's can also be protected with throttleRequests from angel_security.

*Note: See VirusTotal's TOS. They do not allow use of their public API in commercial products. However, you can pay to use their private API.
