hash

README

hash

This package is used to calculate file hash.

The NewWithOs method will automatically call the os.File.Close() method by default. To prevent the call, see the following example.

package main

import (
    "fmt"
    "os"

	"github.com/3JoB/ulib/fsutil/hash"
)

func main(){
    y, err := os.Open("GMakefile.yml")
    if err != nil {
        return nil
    }
    md5, _ := hash.NewWithOs(y).DisableAutoClose().MD5()
    fmt.Println(md5)
}
