Hash Generator

Hash text with SHA-256 or SHA-1 in your browser. No data leaves your device.

Enter text and get SHA-256 and SHA-1 hashes for checksums, quick comparisons, or learning. Hashing runs locally in your browser.

How to use this tool

Paste or type the text you want to hash.
Trigger hash (or the on-page action).
Copy the digest you need (SHA-256 is preferred for modern use).

Tips

SHA-1 is legacy for many security contexts; prefer SHA-256 for new work.
Hashes are one-way—you cannot recover the original text from the digest.
Pair with UUID generator when you need unique IDs instead of hashes.

FAQ

Is my text sent to your servers?

No. Hashing is performed on your device in the browser.

Can I hash files?

This page hashes text. For files, hash a file in dedicated software—or paste Base64 from Image to Base64 only if you understand the tradeoffs (large text).

Is SHA-256 enough for passwords?

For password storage, sites should use slow algorithms (bcrypt, Argon2, scrypt), not plain SHA-256. This tool is for checksums and learning, not production password databases.
