What Is BLAKE1-512?

BLAKE1-512 is a 512-bit hash function from the original BLAKE family, a SHA-3 finalist using 64-bit words and 16 rounds with optional salt parameter. It is rarely used today, superseded by BLAKE2b and BLAKE3.

Specifications

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

Use Cases

  • SHA-3 finalist research and comparison
  • Legacy BLAKE1 512-bit compatibility
  • Applications requiring large-output BLAKE1
  • Cryptographic evolution study
  • Historical system maintenance
!

Security Notice

BLAKE1 is superseded by BLAKE2 and BLAKE3. For new 512-bit hashing, use BLAKE2b or BLAKE3. BLAKE1 should only be used for legacy compatibility.

How to Generate a BLAKE1-512 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 BLAKE1-512 options if your use case requires non-default settings.
  4. Click Generate BLAKE1-512 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 BLAKE1-512

  • Do not use a plain hash or derivation output directly as password storage without the right password-hashing construction and parameters.
  • For new systems, prefer BLAKE2b or BLAKE3 unless compatibility requires BLAKE1.

Recommended Alternatives

Review related tools when you need a different output size, security margin, or keyed construction.
