The bytes must match exactly

An SRI hash covers the exact bytes the browser downloads. Re-minifying, changing line endings, or adding a trailing newline produces a different digest and the browser will block the resource. Upload the built file rather than retyping it.

Privacy & Security

All processing happens locally in your browser. Your data never leaves your computer, ensuring complete privacy and security.
