IntegrityScan: Secure and Fast Verification of SHA-256 Hashes and RSA-PSS Digital Signatures

IntegrityScan is an advanced, fully client-side web tool that works entirely offline in the browser, allowing you to quickly, securely, and privately calculate and verify SHA-256 hashes and RSA-PSS digital signatures.
You can check the integrity of files, texts, and SEO reports without ever sending data to external servers, ensuring your privacy and speeding up the process.
The plugin supports file uploads and text input to generate hashes, automatic verification against reference hashes, and validation of digital signatures with PEM-format public keys.
It also includes dedicated features for verifying the integrity of SEO reports and HTML/snippet content — essential tools for SEO specialists and webmasters focused on data security and quality.

How it works:

Select a file or paste text to quickly and securely calculate its SHA-256 hash.
Enter a reference hash to automatically verify content integrity and match.
Provide a public key, digital signature, and signed data for full RSA-PSS signature verification.
Use dedicated sections to upload SEO reports or paste SEO content and check their integrity without any risk of data loss.
All operations run offline in the browser, with no data sent to external servers.
