For how to use this shard, check the sisiter shard captcha.

These two libraries should be interchangeable without the need to change you code.

The different is:

• SimpleCaptcha has no external dependencies other than Crystal，so, you can built static binary (if this is your's need)
• this shard captcha code only support number.

Installation

1. Add the dependency to your shard.yml:

   dependencies:

       github: crystal-china/simple_captcha
