# Crextractor
Utility for extracting credentials from the Crunchyroll Android app
## Prerequisites
- [Node.js](https://nodejs.org/en)
- [jadx](https://github.com/skylot/jadx)
## Usage
### Fetching already extracted credentials
```js
async function main() {
const url = 'https://raw.githubusercontent.com/vitalygashkov/crextractor/refs/heads/main/credentials.tv.json';
const credentials = await fetch(url).then((response) => response.json());
// You can use the extracted credentials to obtain access tokens for Crunchyroll APIs
const response = await fetch('https://beta-api.crunchyroll.com/auth/v1/token', {
headers: {
Authorization: credentials.authorization,
'User-Agent': 'Crunchyroll/ANDROIDTV/3.42.1_22267 (Android 16; en-US; sdk_gphone64_x86_64)',
// ...
},
method: 'POST',
body: JSON.stringify({
// ...
}),
});
}
```
### Command-line interface
```bash
npx crextractor --target mobile --output ./credentials.mobile.json
```
> Results will be printed to the console and saved to `credentials.mobile.json` file. By default, the target is TV, but you can change it with `--target mobile` option.
### Library
```bash
npm i crextractor
```
```js
import { extract } from 'crextractor';
const { id, secret, encoded, authorization } = await extract();
// id - Crunchyroll app ID
// secret - Crunchyroll app secret
// encoded - Base64 encoded `id:secret` string
// authorization - ready HTTP header in the format `Basic <encoded>`, can be used to access some Crunchyroll APIs
// Do something with the extracted credentials
```
