# `your-main-domain` is what users will enter in their address bar.
# Privileged computation such as key management is handled in this scope
# UI content is loaded via the `your-sandbox-domain`.
# "Content Security Policy" headers prevent content loaded via the sandbox
# from accessing privileged information.
# This setup allows to take advantage of CryptPad's sandboxing techniques.
# In the event of an XSS vulnerability in CryptPad's front-end code
# this will limit the amount of information accessible to attackers.
