About Whirlpool Hash Generator
Whirlpool is a cryptographic hash function designed by Vincent Rijmen (co-creator of AES) and Paulo S. L. M. Barreto, who first described it in 2000. Several variants exist:Whirlpool-0 is the original version released in 2000. Whirlpool-T is the first revision, released in 2001, improving the generation of the s-box. Whirlpool is the latest revision, released in 2003, fixing a flaw in the diffusion matrix.
Input: binary bytes (text input uses UTF-8; a file retains its original bytes). Output: text.

Before interpreting the result
Use a checksum to compare exact bytes against a trusted digest. Choose a password hashing function for passwords and a MAC for keyed authentication. MD5 and SHA-1 are unsuitable for new security-sensitive designs.
How to use this page
- Paste your input or open a local file.
- Adjust tool options if needed, then choose Run tool.
- Copy the result or download the original output bytes.
Inputs and results are not added to the public catalogue or saved in the URL. Processing happens in your browser; HTTP Request and DNS over HTTPS send the requests you explicitly run. Files up to 128 MiB can be opened; decompression and image tools may have smaller processing limits. Large results have a shortened preview. Text and HTML downloads use UTF-8; binary downloads preserve output bytes. Pasted text follows browser newline handling; open a file when exact input bytes matter.
