About Blake2s

Blake2s is a cryptographic hash function that is optimized for 32-bit platforms. It is a variant of the Blake2 family of hash functions, designed to be faster than SHA-2 and SHA-3 while maintaining a high level of security.

Key Features

  • Optimized for 32-bit platforms
  • Supports output lengths from 128 to 256 bits
  • Faster than SHA-2 and SHA-3
  • Supports keyed hashing (MAC)
  • Resistant to length extension attacks
  • Simple and efficient implementation

Common Uses

  • File integrity verification
  • Digital signatures
  • Message authentication codes (MAC)
  • Password hashing
  • Blockchain and cryptocurrency applications

Technical Details

  • Based on the ChaCha stream cipher
  • Uses a 32-bit word size (unlike Blake2b which uses 64-bit words)
  • Maximum output length: 256 bits (32 bytes)
  • Internal state size: 256 bits
  • Block size: 512 bits

Security

Blake2s provides the same security guarantees as Blake2b but is optimized for 32-bit platforms. It is resistant to all known cryptographic attacks and has been extensively analyzed by the cryptographic community.

Comparison with Blake2b

While Blake2b is optimized for 64-bit platforms and can produce longer hashes (up to 512 bits), Blake2s is optimized for 32-bit platforms and is limited to 256-bit outputs. Blake2s is generally faster than Blake2b on 32-bit platforms but may be slower on 64-bit platforms.
