Generate cryptographic SHA-384 & SHA-512 SRI hashes for CDN scripts.
Execution runs 100% locally inside the browser sandbox using HTML5 Canvas, Web Cryptography Subtle API, and Web Workers. Zero egress.
Zero network latency. Operates completely offline with zero dependencies on third-party backend servers or cloud services.
Built according to official RFC specifications, cryptographic test vectors, and enterprise-grade data transformation standards.
Paste the raw contents of your JavaScript or CSS file.
Provide the public CDN address of the hosted resource.
Copy the HTML tag with integrity='sha384-...' and crossorigin='anonymous'.
SRI ensures that browsers will refuse to execute CDN files if they are modified or compromised by an attacker.
W3C recommends SHA-384 for optimal security and performance.
