Hash text with SHA-256
SHA-256 produces a 64-character fingerprint of any input and is the workhorse of modern integrity checks — used to verify downloads, index content, and compare values safely. The same input always yields the same digest, and you can't reverse it. This tool computes SHA-256 (and related SHA variants) of your text directly in the browser.
How to use it
- Paste the text you want to hash.
- Read the SHA-256 digest, or switch to another variant.
- Copy the hash to compare or record it.
What it's good for
- Verifying that a file or message matches a published checksum.
- Creating a stable, fixed-length key from a longer value.
- Comparing two inputs without storing them directly.
Questions people ask
Can SHA-256 be reversed? No — it's one-way. For short, guessable inputs, though, an attacker can try candidates, so it alone isn't enough to protect passwords.
Is my text sent anywhere? No — hashing uses your browser's crypto engine locally.
