Question 1

How do I integrate Base64Captcha with a custom database like Redis?

Accepted Answer

Implement the Store interface provided by the library. The README includes an example with etcd, which you can adapt for Redis by creating a similar store that handles set, get, and verify operations for captcha data.

Question 2

Base64Captcha vs dchest/captcha: which is better for Go projects?

Accepted Answer

Base64Captcha offers more built-in types like math and Chinese captchas, plus base64 output, while dchest/captcha is simpler and more minimal. Choose Base64Captcha if you need extensibility and diverse captcha options; otherwise, dchest/captcha might suffice for basic needs.

Question 3

Does Base64Captcha support audio captchas for accessibility?

Accepted Answer

Yes, it includes a DriverAudio for generating audio captchas as base64-encoded strings. You can configure it in your code to provide auditory challenges, as mentioned in the captcha type options.

Question 4

How to generate a math equation captcha with Base64Captcha?

Accepted Answer

Use the built-in DriverMath. In your implementation, set the captcha type to 'math' and pass the driver configuration, similar to the example in the README where different drivers are switched based on request parameters.

Question 5

Is Base64Captcha production-ready for high-traffic sites?

Accepted Answer

It can be, but you must replace the default memory store with a scalable backend like Redis or etcd. The library itself is stable, but performance depends on your custom storage implementation and server setup.

Question 6

How to use Base64Captcha with the Gin web framework?

Accepted Answer

Follow the HTTP server example in the README. Create handlers for generating and verifying captchas, then integrate them into Gin's routes using the same library methods, adjusting for Gin's context and response handling.
