Whirlpool Hash Generator and Lookup
Understanding Whirlpool
Whirlpool is a cryptographic hash function that produces a 512-bit digest, written as 128 hexadecimal characters. It uses a different construction from SHA-512 despite having the same output length.
Digest size512 bits
Common format128 hexadecimal characters
Generation and database lookup
The generator converts your input into a Whirlpool digest. A hash is not reversible encryption: recovering text requires a known candidate or an indexed match.
Security guidance
Whirlpool can be used for integrity checking, but it is far less common than SHA-2 or SHA-3. It is not specifically designed to slow password guessing; use a dedicated password KDF for stored passwords.
FAQ
How long is a Whirlpool hash?
Whirlpool produces 512 bits, normally displayed as 128 hexadecimal characters.
Are Whirlpool and SHA-512 the same?
No. They share an output length but use different cryptographic constructions.
Is Whirlpool suitable for passwords?
Not by itself. Use a salted, deliberately slow password function such as Argon2id, scrypt or bcrypt.
Practical notes
Whirlpool produces a 512-bit digest. It can verify integrity, but it is not a password-derivation function.

Frequently asked questions
Is Whirlpool reversible?
No. A lookup can only return a previously known match.
Is it related to SHA-512?
No. The output length is the same, but the cryptographic construction differs.
Can it be used alone for passwords?
It is not recommended; prefer a slow function with a salt and configurable cost.
