Generate a SHA-256 hash
Type or paste text above and its SHA-256 hash is computed instantly as a 64-character hex string. SHA-256 is a widely used one-way hash for checksums, fingerprints and verifying that data has not changed. The hashing uses your browser secure cryptography, so the text never leaves your device.
One-way by design
A hash cannot be reversed back into the original text. The same input always produces the same hash, which is what makes it useful for verification.
Frequently asked questions
Can a SHA-256 hash be reversed?
No. It is a one-way function, so you cannot recover the original text from the hash.
Is my text uploaded?
No. The hash is computed in your browser using its built-in cryptography, so nothing is sent anywhere.
