See the [examples] directory for a complete example. You can also see the implemented generators, storages, and finders in the source code.
## Storage
The storage of the captcha is handled by a [`CaptchaStore`] trait. You can implement your own storage or use the [`cacache-rs`] by enabling the `cacache-storage` feature.
There is a default storage, which is [`MemoryStorage`] it's a simple in-memory storage. You can implement your own storage by implementing the [`CaptchaStorage`] trait.
### Cacache Storage
A high-performance, concurrent, content-addressable disk cache. The storage is based on [`cacache-rs`] crate. to use it, you need to enable the `cacache-storage` feature.
```toml
[dependencies]
salvo-captcha = { version = "0.1", features = ["cacache-storage"] }
salvo-captcha = { version = "0.2", features = ["cacache-storage"] }
```
## Captcha name and difficulty
## Captcha Finder
We provide fully customizable query parameters, form fields, and headers to find the captcha token and the captcha answer. You can implement your own finder by implementing the [`CaptchaFinder`] trait.
## Captcha Generator
We provide [`SimpleCaptchaGenerator`] which is a simple captcha generator based on the [`captcha`] crate. You can implement your own captcha generator by implementing the [`CaptchaGenerator`] trait.
