About MurmurHash Algorithm

MurmurHash is a non-cryptographic hash function developed by Austin Appleby in 2008. It is optimized for speed and designed for use in hash-based lookup operations like hash tables. The name comes from the basic operations it uses: multiply (MU) and rotate (R), hence MURMUR.

MurmurHash Characteristics

• Non-cryptographic: Not designed for security purposes
• High performance: Optimized for speed and efficiency
• Good distribution: Excellent avalanche behavior
• Platform independent: Consistent results across different systems
• Seedable: Customizable initialization for different use cases

⚠️ Important: MurmurHash is a non-cryptographic hash function and should NOT be used for security-sensitive applications like password hashing, digital signatures, or any scenario requiring collision resistance. For security purposes, use cryptographic hash functions like SHA-256 or SHA-3.

Common Uses of MurmurHash

MurmurHash is widely used in various applications where high-performance hashing is required:

Application	Usage
Hash Tables	Fast key hashing for hash-based data structures
Bloom Filters	Efficient probabilistic data structure implementation
Database Systems	Partitioning, sharding, and indexing operations
Caching Systems	Key distribution and cache partitioning
Load Balancing	Consistent hashing for distributed systems

MurmurHash vs Other Hash Algorithms

Algorithm	Type	Speed	Primary Use
MurmurHash	Non-cryptographic	Very Fast	Hash tables, data structures
FNV-1a	Non-cryptographic	Fast	Hash tables, checksums
CityHash	Non-cryptographic	Very Fast	String hashing
SHA-256	Cryptographic	Slow	Security, certificates
MD5	Cryptographic (broken)	Medium	Checksums, legacy systems

MurmurHash Variants

MurmurHash32

32-bit output, ideal for most hash table applications and general-purpose hashing

MurmurHash64

64-bit output, provides better distribution for larger datasets

MurmurHash128

128-bit output, used in specialized applications requiring maximum distribution

💡 For high-performance applications requiring fast hashing with good distribution properties, MurmurHash is an excellent choice. For security-critical applications, always use cryptographic hash functions like SHA-256 or SHA-3.
