What Is Keccak-512?

Keccak-512 is the original Keccak submission variant producing 512-bit output using Keccak-f[1600] with capacity 1024 and domain suffix 0x01, differing from SHA3-512 only in the padding suffix.

Specifications

Output Size 512 bits
Standard Keccak submission to NIST SHA-3 competition
Standard Year 2008

Use Cases

  • Original Keccak specification compliance
  • Maximum output length Keccak variants
  • Research and academic applications
  • Alternative padding to SHA3-512
  • High-security hashing requirements

Security Notice

Keccak-512 is suitable for cryptographic integrity checks and fingerprints when used appropriately. Use HMAC or KMAC when you need message authentication, and use a dedicated KDF such as Argon2, bcrypt, or scrypt for password storage.

How to Generate a Keccak-512 hash

  1. Choose UTF-8, Hex, Base64, or File input mode.
  2. Enter text, encoded bytes, or choose a local file to process.
  3. Adjust the Keccak-512 options if your use case requires non-default settings.
  4. Click Generate Keccak-512 Hash and copy the result.

Example Input

Sample input:

abc

Use this sample input, then copy the generated hash from the result panel.

When Not to Use Keccak-512

  • Do not use a plain hash or derivation output directly as password storage without the right password-hashing construction and parameters.
