BLAKE2 Hash Generator

Generate BLAKE2b and BLAKE2s hash values for your text or files

100% Client-Side Processing

All file hashing happens directly in your browser. Files are never uploaded to any server, ensuring complete privacy and security for sensitive data. Our implementation produces hash values that are bit-for-bit identical to those generated by command-line tools.

About BLAKE2

BLAKE2 is a cryptographic hash function that's faster than MD5, SHA-1, SHA-2, and SHA-3, yet is at least as secure as the latest standard SHA-3. It was designed by Jean-Philippe Aumasson, Samuel Neves, Zooko Wilcox-O'Hearn, and Christian Winnerlein.

BLAKE2 comes in two variants:

  • BLAKE2b (or BLAKE2b) - Optimized for 64-bit platforms, produces digests of any size between 1 and 64 bytes
  • BLAKE2s (or BLAKE2s) - Optimized for 8- to 32-bit platforms, produces digests of any size between 1 and 32 bytes
