Whirlpool Hash Generator
Generate the 512-bit Whirlpool hash of any text.
Your browser has no built-in Whirlpool function, so the text is sent securely to our server to be hashed. It is not stored or logged. Avoid hashing real passwords or secrets with online tools.

How to use the Whirlpool Hash Generator
Whirlpool is a cryptographic hash function designed by Vincent Rijmen, co-creator of AES, and Paulo Barreto. It produces a 512-bit hash written as 128 hexadecimal characters and is adopted in the ISO/IEC 10118-3 standard. Browsers do not include Whirlpool, so the text is hashed on our server with PHP and nothing is stored.
- 1 Type or paste your text.
- 2 Wait a moment for the 128-character Whirlpool hash to appear, then copy it.
- 3 Paste a known hash into the compare box to check a match.
Example and practical tips
Hashing an empty string with Whirlpool gives a result starting with 19fa61d75522a4669b44e39c1d2e1726, a quick way to check other implementations.
Frequently asked questions
Can a Whirlpool hash be decrypted?
No. Hashing is one-way: there is no key to reverse it. Short or common inputs can sometimes be found by guessing and comparing hashes, which is why hashes alone should not protect passwords.
Why does a tiny change give a completely different hash?
Hash functions are designed so that changing even one character, or its case, changes the output completely. That makes them good for spotting any modification to data.
What is Whirlpool used for?
Some file integrity tools, TrueCrypt and VeraCrypt key derivation and systems that follow the ISO/IEC 10118-3 standard. SHA-256 and SHA-512 are far more common today.
