Generate W3C-compliant SHA-256, SHA-384, and SHA-512 integrity hashes for CDN assets.
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 your script/CSS code, upload a local file, or fetch a remote CDN URL.
The tool uses browser-native Web Crypto API to generate SHA-256, SHA-384, and SHA-512 base64 digests.
Copy the pre-configured <script> or <link> tag with integrity and crossorigin attributes.
SRI is a W3C security standard that enables web browsers to verify that files fetched from CDNs or third-party servers have not been manipulated or compromised.
The W3C specification recommends SHA-384 as the sweet spot between cryptographic collision resistance and performance.
