What is Subresource Integrity?

A mechanism for ensuring that resources loaded from external sources have not been tampered with.

How do I use SRI Hash Generator?

Provide URLs of your external resources, then the tool will generate corresponding integrity hashes.

Yes, but ensure you upload correct files or URLs to get reliable hash values.

What alternatives exist?

Manual calculation using command-line tools like OpenSSL for generating SHA-256/SHA-384 hashes.

Does it protect privacy?

Absolutely, all operations are performed locally in your browser with no data transmitted.

About This Tool

The Subresource Integrity (SRI) Hash Generator creates hashes for external resources to ensure they have not been tampered with during transit. It is crucial for web developers who want to secure their applications against malicious scripts and other attacks.

Users upload or provide URLs of external resources, such as JavaScript files or CSS stylesheets, and the tool generates SRI hashes based on SHA-256 or SHA-384 algorithms. The output includes integrity attributes that can be added to HTML tags for verification purposes.

Useful in scenarios where third-party scripts are integrated into web pages but need to maintain security standards. This browser-based solution ensures privacy by running calculations locally, with no data transmitted during use.
