About xxHash
What is xxHash?
xxHash is an extremely fast non-cryptographic hash algorithm that operates at speeds close to RAM speed limits. Created by Yann Collet, it is widely used in scenarios requiring high speed. xxHash provides excellent distribution and collision resistance (for non-security purposes).
Algorithm Variants
- xxHash32: 32-bit hash output, fastest on 32-bit systems, uses a single 32-bit seed
- xxHash64: 64-bit hash output, optimized for 64-bit systems, supports 64-bit seed
- xxHash3 (64-bit): Latest generation algorithm, optimized for small data and SIMD, 64-bit output
- xxHash128: 128-bit hash output, based on xxHash3 algorithm, highest collision resistance
Common Use Cases
- File integrity verification and deduplication
- Hash table implementation with excellent distribution
- Database indexing and caching systems
- Bloom filters and probabilistic data structures
- Game resource verification and data stream processing
Security Notice
xxHash is not a cryptographic hash function. Do not use it for password hashing, digital signatures, or any security-sensitive applications. For security purposes, use SHA-256, SHA-3, BLAKE3, or other cryptographic hash functions.
