About this tool
Generate Subresource Integrity (SRI) hash values for JavaScript and CSS content using SHA-256, SHA-384, and SHA-512. Copy ready-to-use integrity strings for script or link tags to improve resource tamper protection. Ideal for CDN assets, security hardening, and release verification workflows.
Frequently Asked Questions
What is SRI used for?
