Abstract
In some examples, a system for server-side rendering of password-protected files can receive, from a client device, a request to view a file on the system, determine that the file should be converted to a different format prior to presentation at the client device, and determine that the file is a password-protected file. The system can send a response to the client device indicating the file is a password-protected file. In response to receiving the password from the client device, the system can generate, based on the password, a preview of the password-protected file including at least a portion of the password-protected file rendered in the different format. After generating the preview, the system can store an encrypted copy of the preview in storage for future requests, and send the preview to the client device.
