### 具有特定名称的单个 cookie

cookie-monster -c eyJmb28iOiJiYXIifQ== -s LVMVxSNPdU_G8S3mkjlShUD78s4 -n session
```

### 自定义字典

```bash
cookie-monster -c eyJmb28iOiJiYXIifQ== -s LVMVxSNPdU_G8S3mkjlShUD78s4 -w custom.lst
```

### 使用批处理模式测试多个Cookie

```bash
cookie-monster -b -f cookies.json
```

### 使用自定义字典批量测试多个cookie

```bash
cookie-monster -b -f cookies.json -w custom.lst
```

### 编码并签署一个新的cookie

如果你知道密钥，你可以签署这个cookie。

```bash
