Hash Generator — free online tool
Verify file integrity or compare checksum algorithms (MD5, SHA-256, SHA-3, and more) with hex or Base64 output.
When to use Hash Generator
Fingerprint files or strings with SHA/MD5 for checksums—not for storing passwords.
Useful when you want a quick answer without pasting sensitive data into random chat bots.
What Hash Generator does not do
Checksums only—never hash passwords with MD5/SHA-1 for storage. Not an HMAC or bcrypt tool.
How to use Hash Generator
- Paste the string or small file text you want to fingerprint into Hash Generator.
- Select algorithms (MD5, SHA-256, SHA-3, etc.) if multiple outputs are offered.
- Generate hex or Base64 digests in the browser.
- Compare checksums with a CLI tool when verifying downloads.
Practical tips
- Use SHA-256 or stronger for integrity checks; MD5 and SHA-1 are broken for security.
- Hashing is one-way—it verifies data, it does not encrypt or hide it reversibly.
- Compare a downloaded file’s hash against the publisher’s value to detect tampering.
Example
SHA-256 a release ZIP name to publish a checksum on a download page.

Limitations
Computes in the browser; huge files may stall. MD5/SHA-1 are shown for compatibility, not password storage.

Give me a concrete example for the Hash Generator.
SHA-256 a release ZIP name to publish a checksum on a download page.
Why did the Hash Generator fail or look wrong?
Try a smaller file, fewer pasted characters, or an updated browser. Extensions that block scripts or downloads sometimes interfere—test in a private window if results never appear.

Cryptographic hash generator
Web Crypto (SHA-1…512) + CryptoJS (MD5, SHA-224, RIPEMD-160, SHA3…). Output: hex, Base64, URL-safe Base64 — or all at once.
CryptoJS algorithms load once from cdnjs (~200 KB). SHA3 needs a modern CryptoJS bundle.
