Can I concatenate multiple non-crypto hash functions to reduce collision?

  XXH3 algorithm in Go

xxhash3 can supply hashes up to 128 bits and supports seeds and has pretty good speed on short inputs.

• highwayhash

  2 856 1.9 Go

  Native Go version of HighwayHash with optimized assembly implementations on Intel and ARM. Able to process over 10 GB/sec on a single core on Intel CPUs - https://en.wikipedia.org/wiki/HighwayHash (by minio)

  

highwayhash (alt) provides 256 bits. Fast mainly for larger inputs and supports seeds.

• sha256-simd

  3 933 1.0 Go

  Accelerate SHA256 computations in pure Go using AVX512, SHA Extensions for x86 and ARM64 for ARM. On AVX512 it provides an up to 8x improvement (over 3 GB/s per core). SHA Extensions give a performance boost of close to 4x over native.

  

SHA256 is high quality but typically a bit slower. Next Go version will have faster SHA256 on some amd64 CPUs - until then you can try sha256-simd which offers the same.
