SMHasher is a C++ test suite that evaluates the distribution, collision, and performance properties of non-cryptographic hash functions. It is also the home of the MurmurHash family of hash functions, including MurmurHash3.
Use cases
- test the quality of a non-cryptographic hash function
- benchmark hash function speed and collision rates
- find flaws in popular hash functions
- get a fast general-purpose hash like MurmurHash3
- compare 32-bit and 128-bit hash implementations
When to choose
- you need to validate or benchmark a non-cryptographic hash function
- you want a well-tested general-purpose hash like MurmurHash3 for hash tables or checksums
When to avoid
- you need a cryptographic or secure hash function
- you need a maintained library with a formal license for the test suite itself
