- 1Enter your text
Type or paste the text you want to hash into the box.
- 2Read the hashes
MD5, SHA-1, SHA-256, SHA-384 and SHA-512 are calculated instantly as you type.
- 3Copy the one you need
Each algorithm has its own Copy button for the hex digest.
Examples
| Input | Output |
|---|---|
hello | MD5: 5d41402abc4b2a76b9719d911017c592 |
hello | SHA-256: 2cf24dba5fb0a30e26e83b2ac5b9e29e1b161e5c1fa7425e73043362938b9824 |
Free online hash generator
This hash generator instantly creates MD5, SHA-1, SHA-256, SHA-384 and SHA-512 hashes from any text. Hashing is one-way — the same input always produces the same fixed-length output, which is why hashes are used for checksums, data integrity and fingerprinting.
Common uses
- Verify a file or message has not changed (checksum).
- Fingerprint data for caching or deduplication.
- Compare values without storing the original text.
Everything is computed locally in your browser, so even sensitive input stays private.
Frequently Asked Questions
Which hash algorithms are supported?
MD5, SHA-1, SHA-256, SHA-384 and SHA-512. Hashes are recalculated instantly as you type.
Is my text sent to a server?
No. SHA hashes use your browser's built-in Web Crypto API and MD5 runs in JavaScript on your device. Nothing is uploaded.
Is MD5 or SHA-1 secure?
MD5 and SHA-1 are fine for checksums and non-security uses, but they are considered broken for cryptographic security. For passwords or signatures use SHA-256 or stronger.
Can I reverse a hash back to the original text?
No. Hashing is one-way by design — you cannot decrypt a hash. Matching is done by hashing a guess and comparing it to the stored hash.
What is a hash used for?
Verifying file integrity (checksums), storing password fingerprints, deduplicating data, and generating cache keys. The same input always produces the same hash.
Why do the same words always give the same hash?
Hash functions are deterministic: identical input always produces identical output. That is what makes them useful for verifying that data has not changed.
