SRI Hash Generator అంటే ఏమిటి?

Subresource Integrity (SRI) is a security feature that lets browsers verify that resources fetched from CDNs haven't been tampered with. You add an integrity attribute to script or link tags with a hash of the expected file content.

This tool generates SRI hashes (SHA-256, SHA-384, SHA-512) for any URL or file content. It creates the complete integrity attribute value and the HTML tag with crossorigin attribute.

FAQ

What hash algorithm should I use?
SHA-384 is recommended as a good balance of security and compatibility. SHA-512 provides the most security.
Do I need crossorigin?
Yes — the crossorigin='anonymous' attribute is required for SRI to work with cross-origin resources.
