How to generate hash number of a string in Go?

Question

For example:

hash(\"HelloWorld\") = 1234567

Is there any built-in function could do this ?

Thanks.

Answer 1

Here is a function you could use to generate a hash number:

// FNV32a hashes using fnv32a algorithm
func FNV32a(text string) uint32 {
    algorithm := fnv.New32a()
    algorithm.Write([]byte(text))
    return algorithm.Sum32()
}

I put together a group of those utility hash functions here: https://github.com/shomali11/util

You will find FNV32, FNV32a, FNV64, FNV64a, MD5, SHA1, SHA256 and SHA512
