STEPS

  1. Create file with 192 bytes length:
123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012
  1. Try to HashDistance() with some random file:
package main
import (
	"github.com/glaslos/ssdeep"
	"fmt"
)
func main() {
	deepMaingo := ssdeep.NewSSDEEP()
	deepMaingoStr := deepMaingo.Fuzzy("main.go")
	fmt.Printf("deepMaingoStr: '%s'\n", deepMaingoStr)
	deep192 := ssdeep.NewSSDEEP()
	deep192Str := deep192.Fuzzy("192.txt")
	fmt.Printf("deep192Str : '%s'\n", deep192Str )
	distance, err := ssdeep.HashDistance(deepMaingoStr, deep192Str )
	fmt.Printf("Distance: '%d' Error: '%s'\n", distance, err)
}

ACTUAL RESULT
Error 'Apples != Grapes' is unclear:

block size: 3, file size: 192, n/bs: 64
deep192Str: '3:OWGukOWGukOWGukOWGukOWGukOWGukOWGukOWGukOWGukOWGukOWGukOWGukOWGU:OWGukOWGukOWGukOWGukOWGukOWGukOw,"192.txt"'
Distance: '0' Error: 'Apples != Grapes'
