SRI Hash Generator
Create Subresource Integrity hashes from exact local resource content.
Generate Subresource Integrity values
SRI lets a browser verify that a fetched script or stylesheet matches an expected cryptographic digest. Hash the exact bytes that the deployed URL returns.
Any content change requires a new integrity value, and cross-origin resources generally also need compatible CORS behavior.
How to use the SRI Hash Generator
- Complete the available options using values appropriate for your project.
- Generate the result and read it before copying or downloading it.
- Test the generated output in a safe environment before production use.
Practical example
Review the result against the needs of the specific website or account instead of treating a generated value as a complete security review.
What this tool cannot guarantee
A focused browser tool cannot replace layered security controls, current software, monitoring or a professional assessment.
