xxHash is a non-cryptographic hash algorithm designed for performance and speed. It was created by Yann Collet in 2012 and is widely used in various applications, including:
can process data at tens of gigabytes per second, often reaching the physical speed limits of your RAM. xxhash vs md5
| Feature | MD5 | xxHash (XXH3) | | :--- | :--- | :--- | | | 128 bits (16 bytes) | 32, 64, or 128 bits | | Speed | Slow (300 MB/s) | Extremely Fast (30+ GB/s) | | Cryptographic Security | Broken (Not secure) | None (Zero security) | | Collision Resistance | Moderate (Adversarial possible) | Low (Trivial if targeted) | | Avalanche Effect | Good | Excellent (Better than MD5) | | Use Case | Legacy checksums, non-adversarial dedup | Databases, Hash Tables, Networking, Compression | | Standardization | RFC 1321 | None (Community standard) | xxHash is a non-cryptographic hash algorithm designed for
xxHash comes in variants:
To understand the difference, imagine hashing a 1GB video file. non-adversarial dedup | Databases
