Free SHA-256 / SHA-384 / SHA-512 Hash Generator
Cryptographic hash functions transform input into a fixed-size digest and are useful for integrity checks, cache keys, comparisons and development workflows. This tool uses the browser's Web Crypto implementation of SHA-256, SHA-384 and SHA-512 and returns the digest as hexadecimal text.
How to use it
- Paste or type the value you want to process.
- Choose the operation or algorithm when the tool offers options.
- Generate the result locally in your browser, then copy it without uploading the input to Ciatto Tools.
How to read the result
The same input and algorithm produce the same digest. A different hash means the input or selected algorithm differs, but matching hashes alone do not prove who created the original content.
Limitations
A hash is not encryption and cannot be reversed to recover the original value. Do not use a plain fast SHA hash as a password-storage scheme; password hashing requires dedicated slow, salted algorithms and appropriate server-side controls.
Frequently asked questions
Can I decrypt a SHA-256 hash?
No. SHA-256 is a one-way hash function, not an encryption format.
Does the text get uploaded?
No. The digest is generated locally using Web Crypto in your browser.
