Module: SmartSMS::VerificationCode

Defined in:
lib/smart_sms/helpers/verification_code.rb

Overview

This module provides some methods to generate random verification code

Algorithm:

* short:    Generate short code with 4 numbers
* simple:   Generate simple code with 6 numbers
* middle:   Generate middle complex code of 6 charactors with mixed numbers and letters
* complex:  Generate complex code of 8 charactors with mixed numbers, letters or special charactors
