Hash Generator is a 100% free, browser-based utility that enables you to md5, sha-1, sha-256, sha-384 & sha-512 for text or files. Unlike traditional cloud converters, all processing executes locally on your device with zero server uploads, delivering immediate results and ironclad data privacy.
About the Hash Generator
A cryptographic hash turns any input into a fixed-length fingerprint. The same input always gives the same hash, and the smallest change gives a completely different one. Hashes are used to verify downloads, detect duplicate files, and build caches and signatures.
This generator computes MD5, SHA-1, SHA-256, SHA-384 and SHA-512 at once for text you type or for a file you choose. File hashing uses the browser's built-in Web Crypto API, so even large files are processed locally without uploading. Paste an expected checksum to compare it instantly.
How to use the Hash Generator
- Type text, or switch to File and choose a file.
- All hashes are calculated instantly.
- Paste an expected checksum into "Compare" to verify a match, then copy the hash you need.
Features
- 5 algorithms at once
- Text or file input
- Checksum comparison
- Upper or lowercase hex
Why Choose In-Browser Hash Generator vs Cloud Converters?
| Feature | Toolora (In-Browser) | Traditional Cloud Tools |
|---|---|---|

| File Size Limits | Unlimited (Limited only by your RAM) | Restricted (e.g. 10MB–50MB caps) |
| Processing Speed | Instant (Zero upload/download delay) | Slow upload & queue waiting |
| Ads & Popups | Clean, distraction-free | Heavy banner & interstitial ads |
Frequently asked questions
Which hash algorithm should I use?
Use SHA-256 or SHA-512 for anything security-related. MD5 and SHA-1 are broken for security purposes but are still fine for quick checksums and detecting accidental changes.
Can I hash passwords with this?
Plain hashes are not suitable for storing passwords. Use a slow, salted algorithm such as bcrypt, scrypt or Argon2 on your server.
Is text hashed as UTF-8?
Yes. Text is encoded as UTF-8 before hashing, which matches the behaviour of most programming languages and command-line tools like sha256sum.
