Text hash generator
Paste any text and instantly generate its hash. Supports SHA-256, SHA-1, SHA-384, and SHA-512. Your text is hashed locally and never sent anywhere.
100% local.Your text is hashed in your browser and is not stored or sent anywhere.
Common uses for text hashing
- Verify message integrity — compare hashes to confirm a message has not changed.
- Data deduplication — detect duplicate text entries by comparing hashes.
- API signatures — generate hashes for request verification.
- Unique identifiers — create consistent identifiers from text content.
Frequently asked questions
- What is a text hash?
- A text hash is a fixed-length string generated by a cryptographic algorithm from any input text. The same text always produces the same hash, and even a small change produces a completely different hash.
- Can I use this for passwords?
- You can generate a hash from any text, but this tool is not a password manager. For password storage, use a dedicated password manager that adds a salt. Simple hashing without a salt is not secure for passwords.
- What algorithms are available?
- SHA-256, SHA-1, SHA-384, and SHA-512. SHA-256 is the most commonly used. All are computed using the Web Crypto API in your browser.
- Is my text saved or sent anywhere?
- No. The hash is computed entirely in your browser using the Web Crypto API. Your text is never stored, sent, or logged.
