🔒 100% Client-Side • No File Uploads

#️⃣ Hash Generator & Verifier

Q: Do you collect any data?

We use Google Analytics to track page views, but we never see, store, or collect your files or text. All processing happens locally in your browser.

Generate cryptographic hashes for text and files locally in your browser. Verify file integrity with MD5, SHA-1, SHA-256, and SHA-512 algorithms.

How to Use the Hash Generator

Choose between text hash or file hash mode using the tabs

For text: enter your text. For files: drag and drop or click to upload

Select one or more hash algorithms (MD5, SHA-1, SHA-256, SHA-512)

Click "Generate Hash" and copy the resulting cryptographic hashes

Privacy & Security

This hash generator runs entirely in your browser using the Web Crypto API. When you generate hashes for text or files, the processing happens completely on your device. We never upload your files or text to any server, which means your data remains completely private and secure. This is especially important when hashing sensitive files or passwords.

Unlike online hash generators that require file uploads to remote servers, our client-side approach ensures zero data collection, zero server processing, and zero privacy concerns. Your files are processed locally and never transmitted over the internet.

Frequently Asked Questions

What's the difference between MD5 and SHA-256?

MD5 is an older, faster algorithm that's no longer considered cryptographically secure. SHA-256 is part of the SHA-2 family and provides much stronger security. For file integrity verification, SHA-256 or SHA-512 are recommended. MD5 is still useful for non-security purposes like file deduplication.

Can I hash files larger than 100MB?

Yes! Since all processing happens locally in your browser, there's no file size limit imposed by our tool. However, very large files (multi-GB) may take longer to process and could be limited by your browser's memory capabilities.

Are hash functions reversible?

No, cryptographic hash functions are one-way functions. You cannot reverse a hash to get the original input. This property makes them ideal for password storage and data integrity verification. The only way to "crack" a hash is through brute force or rainbow table attacks.

Is this tool really free?

Yes! This tool is completely free with no hidden costs or subscriptions. We believe privacy-first tools should be accessible to everyone.
