Checksums benchmarks

This project was used for research, I want to know which checksum to use (best for all):

• small text
• small binary
• encrypted data

What are we looking for:

• very fast
• low collision rate for small messages

We do not care about the cryptographic hashes, I only need an unique hash for each input.

Algorithms:

• CRC64 checksum https://golang.org/pkg/hash/crc64/
• FNV1 64&128 https://golang.org/pkg/hash/fnv/
• Murmur3 sum 64&128 github.com/spaolacci/murmur3
• Jenkins 64&128- SpookyHash https://github.com/dgryski/go-spooky Jenkins is a family of fast hash algorithms https://en.m.wikipedia.org/wiki/Jenkins_hash_function
