Hash Generator (SHA-256, SHA-1, SHA-512)
Generate SHA-256, SHA-1, SHA-384 and SHA-512 hashes of text.
The hash appears here.
Generate a cryptographic hash (SHA-256, SHA-1, SHA-384 or SHA-512) of any text. Hashing uses the browser's built-in Web Crypto API, so input never leaves your device.
How to use the Hash Generator
- Paste the text to hash.
- Choose an algorithm (SHA-256 is the default).
- Generate and copy the hex hash.
Frequently asked questions
Why isn't MD5 available?
The browser's Web Crypto API doesn't support MD5 (it's considered broken). SHA-256 is the recommended modern default.
Can I reverse a hash back to the text?
No. Cryptographic hashes are one-way by design — you can't recover the original input from the hash.
