Content Security Policy parser
Split a Content-Security-Policy header into directives and sources.
Result
Add your input, then select Parse policy.
How to use it
Paste one policy value to inspect each directive and its source list. Duplicate directives are highlighted.
What to keep in mind
This is a parser, not a security audit or a browser enforcement simulator. Multiple policies need separate review.
Up to 2 MB per input, with smaller limits for complex operations. Clear removes the current input and result.
