WHIRLPOOL Hash Generator

Summary

WHIRLPOOL is a cryptographic hash function that produces a 512-bit (128 hex character) message digest. Designed by Vincent Rijmen and Paulo Barreto, it is standardized by ISO/IEC 10118-3 and is commonly used for data integrity verification, message authentication, and digital signatures (password storage requires dedicated memory-hard functions like Argon2 or bcrypt). This tool runs the full WHIRLPOOL algorithm entirely in your browser — no data ever leaves your device.

How it works

1. Type or paste your input text into the text area.
2. The WHIRLPOOL hash is computed instantly in your browser using pure JavaScript.
3. The 128-character hexadecimal digest is displayed in the output field.
4. Click "Copy Hash" to copy the result to your clipboard.
5. Toggle uppercase/lowercase output format as needed.
6. Use the "Clear" button to reset both fields.

Use cases

• Verify file or data integrity using a WHIRLPOOL checksum.
• Generate message authentication codes (HMAC-Whirlpool) or digital signatures.
• Compare document fingerprints without revealing content.
• Test hash function behavior during cryptographic research.
• Validate WHIRLPOOL implementations against known test vectors.
• Create unique identifiers for deduplication pipelines.
