Create MD5, SHA-1, SHA-256, SHA-384 and SHA-512 hashes from text or a file, all at once. Everything runs on your device.
How to Use Hash Generator
- Choose text or file. Use the Text tab to type or paste, or the File tab to pick a file from your device.
- The hashes appear instantly. MD5, SHA-1, SHA-256, SHA-384 and SHA-512 are all calculated at once as you type or as soon as the file loads.
- Copy what you need. Each hash has its own Copy button, so you can grab exactly the one you want.
- Compare or verify. Paste a hash next to a known value to check that a file or message has not changed.
Frequently Asked Questions
What is a hash?
A hash is a fixed length fingerprint of your data. The same input always gives the same hash, and even a tiny change produces a completely different result.
Is my text or file uploaded?
No. Everything is hashed in your browser with the Web Crypto API and a small MD5 library, so your data never leaves your device.
Which algorithms are included?
MD5, SHA-1, SHA-256, SHA-384 and SHA-512, all calculated together so you can pick the one your task needs.
Can I hash a file?
Yes. Switch to the File tab and choose any file. The tool reads it locally and shows the hashes, which is perfect for checking downloads.
Is MD5 safe for passwords?
No. MD5 and SHA-1 are fine for checksums and quick comparisons, but for security use SHA-256 or stronger, and for passwords use a dedicated password hash.
What are hashes used for?
Verifying that a download is intact, comparing two files, spotting changes, and building unique keys for data.
