module SmartSMS::VerificationCode
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
Constants
- REGISTERED_ALGORITHMS
