Fast local hashing
Paste or type text into the input pane to generate a Keccak-224 hash instantly. If you paste multiple lines, the tool automatically batches them and generates one Keccak-224 digest per line. This is useful for processing lists of identifiers, verifying multiple payloads, or converting a batch of strings to Keccak-224 at once.
About Keccak-224
Keccak-224 is a cryptographic hash function that belongs to the original Keccak family. It produces a 224-bit fixed-length output, which is represented as a 56-character hexadecimal string.
While Keccak is the underlying algorithm that became the SHA-3 standard, Keccak-224 and SHA3-224 are not the same thing. They use different padding rules and will produce different hashes for the same input. You should use Keccak-224 only when a specific protocol, smart contract, or legacy library explicitly requires the original Keccak implementation.
