About xxHash Algorithm

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.

xxHash Characteristics

• Extremely fast - among the fastest hash algorithms available
• Non-cryptographic - not designed for security purposes
• Excellent distribution - good avalanche effect
• Available in 32-bit and 64-bit variants

⚠️ 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.

Common Uses of xxHash

xxHash is ideal for performance-critical applications where cryptographic security is not required:

Aplicação	Utilização
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
