About FarmHash Algorithm Family

FarmHash is a family of hash functions developed by Google, designed for fast hashing of strings and other data. It provides multiple hash functions optimized for different use cases and processor architectures.

FarmHash Variants

• FarmHash32: 32-bit hash output, suitable for hash tables and similar structures
• FarmHash64: 64-bit hash output, balanced performance and collision resistance
• FarmHash128: 128-bit hash output, highest collision resistance

Key Features

• Optimized for modern processors with SSE4.2 and AES-NI instructions
• Excellent distribution and collision resistance
• Faster than many traditional hash functions
• Portable across different platforms and architectures

💡 FarmHash is particularly well-suited for non-cryptographic applications like hash tables, bloom filters, and data fingerprinting where speed and good distribution are important.

Common Uses of FarmHash

FarmHash is widely used in various applications where fast and reliable hashing is required:

Application	Usage
Hash Tables	Fast key hashing for dictionaries and maps
Bloom Filters	Efficient probabilistic data structures
Data Deduplication	Identifying duplicate data through fingerprints
Load Balancing	Distributing requests across servers

FarmHash vs Other Hash Algorithms

Algorithm	Output Size	Performance	Primary Use
FarmHash32	32 bits	Very Fast	Hash tables, internal use
FarmHash64	64 bits	Fast	General purpose, fingerprints
FarmHash128	128 bits	Good	High-quality fingerprints
MD5	128 bits	Good	Checksums, legacy systems
SHA-256	256 bits	Slow	Cryptography, security

⚠️ Important: FarmHash is designed for non-cryptographic purposes. It should NOT be used for security-sensitive applications like password hashing, digital signatures, or any scenario where collision resistance is critical for security. Use cryptographic hash functions like SHA-256 or SHA-3 for security purposes.

💡 FarmHash excels in performance-critical applications where cryptographic security is not required. It's particularly useful for in-memory data structures, load balancing, and data processing pipelines where speed is essential.
