Subresource Integrity (SRI) is a security feature that enables browsers to verify that resources they fetch (for example, from a CDN) are delivered without unexpected manipulation. It works by allowing you to provide a cryptographic hash that a fetched file must match.
Our SRI Hash Generator makes this process simple. Download the script or stylesheet you're linking from a CDN, upload it here, and the tool will generate the correct `integrity` attribute value for your `<script>` or `<link>` tag. This ensures that if the file on the CDN is ever compromised, the browser will refuse to load it, protecting your users.

Frequently Asked Questions
Why is SRI important?
If you include resources from a third-party CDN, that CDN becomes a potential attack vector. If an attacker gains control of the CDN, they could modify the files and inject malicious code into your website. SRI prevents this by ensuring the file's content matches what you expect.
Which algorithm should I choose?
SHA-384 is often recommended as a good balance of security and performance, but all three options (SHA-256, SHA-384, SHA-512) are currently considered secure. The most important thing is to use SRI in the first place.
