CLI tool which generates random strings (passwords) encoded with base58

go58.go

package main

	  _, err := rand.Read(b)
	  if err != nil {
		  fmt.Println("error:", err)
		  panic(fmt.Sprintf("Can't generate rangom bytes:", err))
	  }
	  return b
}


func main() {
    n := flag.Int("n", 16, "random bytes per string")
    c := flag.Int("c", 1, "generate given number of random strings")
    flag.Parse()
      
   var x big.Int     
   for i := 0; i < *c; i++ {  
     buf := base58.EncodeBig(nil, x.SetBytes(secure_random(*n)))
     fmt.Printf("%s\n", buf)
   }
