xxHash is an extremely fast non-cryptographic hash algorithm, working at speeds close to RAM limits. It was created by Yann Collet and is available in multiple variants including xxHash32, xxHash64, and the newer xxHash3.
⚠️ Important: xxHash is a non-cryptographic hash function. It should NOT be used for security purposes, password hashing, or any scenario where collision resistance is critical. For security applications, use cryptographic hashes like SHA-256 or SHA-3.
xxHash is ideal for performance-critical applications where cryptographic security is not required:
| Application | Usage |
|---|---|
| Checksumming | Fast file integrity verification and data validation |
| Hash tables | High-performance hash tables and data structures |
| Data deduplication | Identifying duplicate data blocks in storage systems |
| Bloom filters | Probabilistic data structures requiring fast hashing |
| Variant | Output Size | Speed | Best For |
|---|---|---|---|
| xxHash32 | 32 bits (8 hex chars) | ⚡⚡⚡⚡ | 32-bit systems, smaller datasets |
| xxHash64 | 64 bits (16 hex chars) | ⚡⚡⚡⚡⚡ | 64-bit systems, general purpose |
| xxHash3 | 64 bits (16 hex chars) | ⚡⚡⚡⚡⚡⚡ | Latest systems, maximum speed |
💡 xxHash is perfect for non-cryptographic use cases where speed is critical. For checksums, hash tables, data deduplication, and other performance-sensitive applications, xxHash provides excellent speed with good distribution characteristics.
