Hash Generator
Generate MD5, SHA-1, SHA-256, and SHA-512 hashes from text instantly. Free online hash generator that runs privately in your browser.
Generate MD5, SHA-1, SHA-256, and SHA-512 hashes from any text. Hashes are handy for checksums, verifying data integrity, and generating fingerprints. The SHA algorithms use your browser's native crypto engine, and every hash is computed locally — your text never leaves your device.
How to use Hash Generator
- Type or paste the text you want to hash.
- The MD5, SHA-1, SHA-256, and SHA-512 hashes appear instantly.
- Click "Copy" next to any hash to place it on your clipboard.
Frequently asked questions
Which hash should I use?
For integrity checks and security, prefer SHA-256 or SHA-512. MD5 and SHA-1 are fine for quick, non-security checksums but are considered cryptographically broken for security uses.
Are the hashes computed correctly?
Yes. SHA hashes use the browser's built-in SubtleCrypto, and MD5 uses a well-tested implementation, so results match standard command-line tools byte for byte.
Can I reverse a hash back to the text?
No. Hashing is one-way by design. This tool only creates hashes; it can't undo them.
Is my input sent to a server?
No. All hashing happens in your browser, so the text you enter stays completely private.
