How to Generate a Hash (SHA-256, SHA-512) From Text
A hash is a fixed-length fingerprint of some data: change one character and the hash changes completely. Hashes are used for checksums, integrity checks, and verifying data hasn’t been tampered with. Kitolity generates them in your browser.

- Open the Hash GeneratorGo to the Hash Generator in your browser.
- Paste your textEnter the text you want to hash.
- Pick an algorithmChoose SHA-256, SHA-512, or another supported algorithm.
- Copy the hashCopy the resulting hash — nothing you paste leaves your device.
What are hashes used for?
Verifying a downloaded file matches its published checksum, detecting whether two pieces of data are identical, and building integrity checks. Because the same input always produces the same hash, you can compare fingerprints instead of the whole data.
Is hashing the same as encryption?
No. Hashing is one-way — you can’t reverse a hash back to the original text. Encryption is two-way (with a key). Use hashing for integrity/fingerprinting, not to store recoverable data.
Frequently asked questions
Which algorithms are supported?
Cryptographic hashes such as SHA-256 and SHA-512.
Is my input private?
Yes — hashing runs entirely in your browser, so nothing you paste is uploaded.
Can I reverse a hash?
No — hashing is one-way by design; it cannot be decoded back to the original text.
