## What it is
A Go library that generates various types of captchas (digits, strings, math, Chinese, audio) and returns them as base64-encoded image or audio strings. It supports pluggable storage backends and drivers, making it easy to integrate captcha verification into web applications.

## Use cases
- add captcha verification to a Go web app
- generate image captcha as base64 string for API responses
- prevent bot signups and spam form submissions
- generate math or arithmetic captchas
- generate Chinese or other unicode character captchas
- generate audio captchas for accessibility
- store captcha answers in Redis or custom store

## When to choose
- you need a captcha generator in a Go backend
- you want captchas delivered as base64 strings without serving image files
- you need customizable drivers and pluggable storage

## When to avoid
- your stack is not Go
- you need modern invisible captcha or behavioral bot detection
- you need a hosted captcha service with managed analytics

## Facets
- artifact type: library
- maturity: stable
- function: image-processing, security, serialization
- domain: security, web-development, backend
- platform: go, cross-platform
- tags: captcha, base64, anti-spam, audio-captcha, arithmetic-captcha, unicode, web-server
