About:
Libb2 is a library providing the BLAKE2 secure hashing function, designed as a high-performance alternative to older algorithms like MD5 and SHA-1. It offers faster computation speeds and supports keyed hashing for message authentication without the overhead of HMAC. The library is highly portable and suitable for applications requiring robust and efficient data integrity verification.
Key Features:
  • High-performance hashing (faster than MD5/SHA-1)
  • Support for both 64-bit and 32-bit architectures
  • Keyed hashing for authentication (BLAKE2s and BLAKE2b)
  • Highly portable C implementation
Use Cases:
  • Cryptographic verification of file integrity
  • High-speed data deduplication
  • Secure password hashing
  • Message authentication codes (MACs)
Alternatives:
  • OpenSSL – Libb2 is specialized for BLAKE2, offering a smaller footprint and potentially faster performance for specific algorithms compared to the general-purpose OpenSSL library.
