Frequently Asked Questions
What is an SRI hash generator?
An SRI hash generator creates Subresource Integrity hashes for external scripts and stylesheets. SRI ensures that CDN-hosted files haven't been tampered with by verifying their content against a cryptographic hash.
How do I generate an SRI hash?
Enter the URL of a script or stylesheet, and the tool fetches the file and generates SHA-256, SHA-384, and SHA-512 hashes along with the complete integrity attribute for your HTML.
Why should I use SRI?
SRI protects against supply chain attacks where a CDN or third-party host is compromised and serves malicious code. It ensures the file your browser loads is exactly what you expect.
How do I use the SRI hash in my HTML?
Copy the generated integrity attribute and add it to your script or link tag. The browser will verify the file's content matches the hash before executing it.
Is this tool free?
Yes, ToolDock's SRI hash generator is completely free, requires no signup, and runs entirely in your browser.
