### **IntegrityScan: Your free tool to verify the integrity of files, text, and web pages — right in your browser**

With **IntegrityScan**, you can check in seconds whether a file, a piece of text, or a webpage has been modified, corrupted, or tampered with. Everything happens **securely and privately**, directly in your browser — **your data is never sent to any external server**.

#### What you can do:

🔍 **Calculate a hash** (SHA-1, SHA-256, SHA-384, or SHA-512) of any file or text you upload

✅ **Compare the generated hash** with a reference one to verify that the content is authentic and unaltered

🛡️ **Verify RSA-PSS digital signatures** using a public key — ideal for confirming the origin of signed documents or encrypted messages

🌐 **Check the integrity of a webpage** by simply entering its URL: the plugin securely fetches the content and displays its SHA-256 hash

📈 **Analyze SEO reports or HTML code** (snippets, meta tags, etc.) to ensure they haven’t been changed over time

📤 **Export a complete report in JSON format** with all your verification results — perfect for audits, backups, or sharing with colleagues

> *⚠️ **Important note on URL usage**:
> Use this function **only on public pages that you are authorized to access**. Do not enter private, internal, login-protected, or paywalled URLs. In short, always comply with the website’s terms of use and robots policy.*

#### Why it’s secure:

- The files and text you upload **stay only on your device**
- Hashing and verification run **entirely offline**, with no external connections
- The only exception is the URL check: in that case, seoproof.org acts as a secure intermediary and **does not store or log any content**

Whether you’re an **SEO specialist**, a **webmaster**, a **content auditor**, or simply someone who wants to verify a file’s authenticity, **IntegrityScan gives you full control — with zero compromise on privacy**.

**Get started now**: select a file, paste some text, or enter a URL.

*Integrity verification has never been this **simple, fast, and secure**.*
