Whirlpool Hash Generator

Whirlpool is a cryptographic hash function designed by Vincent Rijmen and Paulo S. L. M. Barreto. It was first published in 2000, selected for the NESSIE portfolio, and later included in ISO/IEC 10118-3. The standardized Whirlpool function accepts messages shorter than 2^256 bits and produces a 512-bit message digest, commonly represented as 128 hexadecimal characters.

This tool hashes the text entered in the input box in the browser and writes the Whirlpool digest to the output box without sending the text to a server. Because Whirlpool is deterministic, the same exact input text produces the same output every time.

Use this page when you need a quick Whirlpool digest for sample text, legacy compatibility checks, test vectors, or checksum-style comparisons with systems that explicitly require Whirlpool.

The generated value depends on the exact bytes being hashed. Spaces, tabs, punctuation, capitalization, line endings, trailing newlines, and Unicode characters all change the result. The tool hashes text only; it does not read files, decode hexadecimal input as binary data, add salts, create HMACs, manage keys, or provide password storage. For authentication, signatures, password hashing, or protocol integration, use the algorithm, encoding, and reviewed cryptographic library required by that system.
