About Keccak Hash
Keccak is a family of cryptographic hash functions that won the NIST hash function competition in 2012. It was selected to become the SHA-3 standard. Unlike SHA-2, Keccak is based on a sponge construction rather than the Merkle–Damgård construction used by SHA-1 and SHA-2.
Keccak Variants:
- Keccak-224: Produces a 224-bit (28-byte) hash value
- Keccak-256: Produces a 256-bit (32-byte) hash value
- Keccak-384: Produces a 384-bit (48-byte) hash value
- Keccak-512: Produces a 512-bit (64-byte) hash value
Security Notes:
- Keccak is designed to resist collision attacks, preimage attacks, and second preimage attacks
- All processing happens locally in your browser - no data is sent to our servers
- File hashing works for large files using chunked processing to avoid memory issues
