How to generate hash number of a string in Go?

by

The hash package is helpful for this. Note it’s an abstraction over specific hash implementations. Some ready made are found in the package subdirectories.

Example:

package main

import (
        "fmt"
        "hash/fnv"
)

func hash(s string) uint32 {
        h := fnv.New32a()
        h.Write([]byte(s))
        return h.Sum32()
}

func main() {
        fmt.Println(hash("HelloWorld"))
        fmt.Println(hash("HelloWorld."))
}
