## Mitmproxy Usage Guide
|
||
|
|
(By 北野樱奈)
|
||
|
|
|
||
|
|
## Prerequisites
|
||
|
|
1. [Download mitmproxy](https://mitmproxy.org/) and install it.
|
||
|
|
2. Basic knowledge of WireGuard and Python scripting.
|
||
|
|
3. A client device (e.g., Android emulator or smartphone) and a host machine running `mitmproxy`.
|
||
|
|
|
||
|
|
### Installation Steps
|
||
|
|
- **Linux/Mac**
|
||
|
|
```markdown
|
||
|
|
# Ubuntu/Debian
|
||
|
|
|
||
|
|
sudo apt update
|
||
|
|
sudo apt install mitmproxy
|
||
|
|
|
||
|
|
# macOS
|
||
|
|
brew install mitmproxy
|
||
|
|
```
|
||
|
|
- **Windows**: Download the `.exe` installer from [mitmproxy.org](https://mitmproxy.org/) and follow the instructions to complete the installation.
|
||
|
|
|
||
|
|
### Verify Installation
|
||
|
|
Run the following command to verify the installation:
|
||
|
|
```bash
|
||
|
|
mitmproxy --version
|
||
|
|
```
|
||
|
|
|
||
|
|

|
||
|
|
|
||
|
|
## Step 2: Install CA Certificates on Client and Server
|
||
|
|
|
||
|
|
To decrypt HTTPS traffic, the client needs to trust the `mitmproxy` CA certificate.
|
||
|
|
|
||
|
|
### Steps
|
||
|
|
1. Start `mitmproxy` to generate the certificate:
|
||
|
|
```bash
|
||
|
|
mitmdump
|
||
|
|
```
|
||
|
|
2. On the PC, navigate to `C:\Users\YourUser\.mitmproxy` to locate the certificate file (mitmproxy-ca.p12).
|
||
|
|
3. In the `mitmproxy` directory, locate `mitmproxy-ca-cert.crt`.
|
||
|
|
4. Rename `mitmproxy-ca-cert.crt` to `c8750f0d.0`.
|
||
|
|
5. Install the certificate as a system CA.
|
||
|
|

|
### For Android Devices
|
||
|
|
1. Move the certificate to the system CA directory:
|
||
|
|
```bash
|
||
|
|
adb root
|
||
|
|
adb remount
|
||
|
|
adb shell mv /sdcard/c8750f0d.0 /system/etc/security/cacerts/
|
||
|
|
```
|
||
|
|
2. Set the correct permissions:
|
||
|
|
```bash
|
||
|
|
adb shell chmod 644 /system/etc/security/cacerts/c8750f0d.0
|
||
|
|
```
|
||
|
|
3. Reboot the device:
|
||
|
|
```bash
|
||
|
|
adb reboot
|
||
|
|
```
|
||
|
|
|
||
|

|
||

|
|
||
|
|
## Step 3: Download the Redirect Script
|
||
|
|
|
||
|
|
Download the script from the repository.
|
||
|
|
|
||
|
|
### Note: **Make sure to modify the IP address in `redirect_server.py`.**
|
||
|
|
```python
|
||
|
|
import gzip
|
||
|
|
import json
|
||
|
|
from mitmproxy import http
|
||
|
|
|
||
|
|
SERVER_HOST = 'Replace this with your IP'
|
||
|
|
SERVER_PORT = 80
|
||
|
|
|
||
|
|
REWRITE_HOST_LIST = [
|
||
|
|
'ba-jp-sdk.bluearchive.jp',
|
||
|
|
'prod-gateway.bluearchiveyostar.com',
|
||
|
|
'prod-game.bluearchiveyostar.com',
|
||
|
|
# 'prod-notice.bluearchiveyostar.com',
|
||
|
|
# 'prod-logcollector.bluearchiveyostar.com',
|
||
|
|
]
|
||
|
|
```
|
||
|
|
|
||
|
|

|
||
|
|
|
||
|
|
## Step 4: Launch mitmproxy and Load the Script
|
||
|
|
|
||
|
|
Run the following command to start `mitmproxy` with the redirect script:
|
||
|
|
```bash
|
||
|
|
mitmweb -m wireguard --no-http2 -s redirect_server.py --set termlog_verbosity=warn --ignore Your IP
|
||
|
|
```
|
||
|
|
|
||
|
|
### Parameter Explanation:
|
||
|
|
- `-m wireguard`: Use WireGuard as the network layer.
|
||
|
|
- `--no-http2`: Disable HTTP/2 to improve compatibility.
|
||
|
|
- `-s redirect_server.py`: Load the redirect script.
|
||
|
|
- `--set termlog_verbosity=warn`: Set log level to warnings only.
|
||
|
|
|
||
|
|
You can monitor traffic through the `mitmweb` interface at `http://localhost:8081`.
|
||
|
|

|
|
|
||
|
|
## Step 5: Install and Configure WireGuard
|
||
|
|
|
||
|
|
Use WireGuard to route client traffic to `mitmproxy`.
|
||
|
|
|
||
|
|
### Installation Steps
|
||
|
|
- **Android**: [Download WireGuard](https://play.google.com/store/apps/details?id=com.wireguard.android).
|
||
|
|
- **Other Platforms**: Refer to the [official WireGuard installation guide](https://www.wireguard.com/install/).
|
||
|
|
|
||
|
|
### Configuration Steps
|
||
|
|
1. Open the WireGuard client, click the `+` button in the bottom left corner, and select **Scan QR Code**.
|
||
|
|
2. The emulator will display a scanner window. Select **Real-time Screenshot**.
|
||
|
|
3. Position the screenshot over the QR code in the Mitmproxy browser page (accessible via settings).
|
||
|
|
4. Enable the configuration.

## Troubleshooting
|
||
|
|
|
||
|
|
### Error: Client TLS handshake failed. The client does not trust the proxy's certificate for yostar-oversea-netsdk-logging.ap-southeast-1.log.aliyuncs.com (OpenSSL Error([('SSL routines', '', 'ssl/tls alert certificate unknown')]))
|
||
|
|
- Ensure that both the PC and client have the same Mitmproxy certificate installed.
|
||
|
|
- Verify that the Mitmproxy certificate is properly installed on both ends.
|
||
|
|
|
||
|
|
### Android Certificate Disappears After Installation
|
||
|
|
- Use the MT Manager to grant SU (superuser) permissions.
|
||
|
|
- Navigate to `/system/etc/security/cacerts/`.
|
||
|
|
- Locate `c8750f0d.0` and set the permissions to 664. The user group should be set to root.
