Frequently Asked Questions
What is SRI (Subresource Integrity)?▾
SRI is a security feature that allows browsers to verify that files they fetch (like scripts or stylesheets from CDNs) are delivered without unexpected manipulation. It uses cryptographic hashes to ensure integrity.
Which hash algorithm should I use?▾
SHA-384 is the most commonly used and recommended. SHA-256 is also widely supported. SHA-512 provides the strongest security but is less commonly used.
How do I use the generated hash?▾
Add the "integrity" attribute to your <script> or <link> tag along with crossorigin="anonymous". The tool generates the complete tag for you.
Is the content sent to a server?▾
No. If you paste content directly, it is hashed in your browser. If you enter a URL, the content is fetched client-side and hashed locally.
