What Is SHA3-512?

SHA3-512 provides the maximum security level in the SHA-3 family with 256-bit collision resistance, producing a 512-bit hash using Keccak-f[1600] with capacity of 1024 bits.

Specifications

Output Size 512 bits
Standard FIPS 202
Standard Year 2015
Origin Keccak submission to NIST SHA-3 competition
Origin Year 2008

Use Cases

  • Long-term archival security
  • Maximum assurance digital signatures
  • Applications requiring 512-bit output

Security Notice

SHA3-512 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 SHA3-512 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 SHA3-512 options if your use case requires non-default settings.
  4. Click Generate SHA3-512 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 SHA3-512

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