rndstring

Library to generate tokens (or random strings) backed up by golang's cryptographically secure random number generator crypto/rand if available.

Examples:

package main

import "github.com/FMNSSun/rndstring"
import "fmt"

func main() {
	for _, tgName := range rndstring.StringGenerators() {
		tg, err := rndstring.NewStringGenerator(tgName, 8)

		if err != nil {
			panic(err.Error())
		}

		fmt.Printf("%30s\t%s\n", tgName, tg.Generate())
	}

	tg, err := rndstring.NewAlphabetGenerator(4,[]rune("ûüà"))

	if err != nil {
		panic(err.Error())
	}

	fmt.Printf("%30s\t%s\n", "* custom", tg.Generate())

	tgPrefix, err := rndstring.NewAlphabetGenerator(4,[]rune("012"))
	tgTail, err := rndstring.NewAlphabetGenerator(4,[]rune("abcdef"))

	fmt.Printf("%30s\t%s\n", "* join", rndstring.Join("-", tgPrefix, tgTail, tgTail))
}
