What it is AI-extracted, prompt v1, taxonomy v1, 2026-08-30, confidence not recorded
A Go implementation of the 64-bit xxHash (XXH64) algorithm with a simple API including a hash.Hash64-compatible Digest type. It offers optimized pure Go code plus faster assembly implementations for amd64 and arm64.
Use cases
- fast non-cryptographic hashing in Go
- hash table key hashing for caches
- checksumming data quickly
- implementing hash maps or bloom filters
- replacing slow standard library hashing
When to choose
- you need a very fast 64-bit non-cryptographic hash in Go
- you want hash.Hash64 compatibility
- you need proven production use (used by Prometheus, InfluxDB, Badger)
When to avoid
- you need cryptographic security (use SHA-256 or similar)
- you need XXH3 or 32-bit variants
- you are not working in Go
