Golang RandomPassword Examples

Example #1

File: accounts.go Project: masom/doorbot

// generateHost generates a host that isn't yet taken.
func generateHost(r doorbot.Repositories, config *doorbot.DoorbotConfig) (string, error) {
	repo := r.AccountRepository()

	// Generate a random valid host name
	for i := 0; i < 10; i++ {
		tmp := strings.ToLower(security.RandomPassword(10))

		exists, err := repo.FindByHost(r.DB(), tmp)
		if err != nil {
			log.WithFields(log.Fields{
				"error": err,
				"host":  tmp,
			}).Error("Api::Accounts->Register database error.")

			return "", err
		}

		if exists == nil {
			return tmp, nil
		}
	}

	return "", nil
