About this app
Simple and open-sourced SSTP VPN client
This is a VPN client app for Secure Socket Tunneling Protocol.
Features:
- Simple for maintainability
- No Ads
- Open source (https://github.com/kittoku/Open-SSTP-Client)
Tips:
With the app's notifications allowed, you can get error messages and disconnect easily. Also, you can connect/disconnect from Quick Settings panel.
License:
This app and its source code are under MIT License. I'll do my best, but be sure that you use this app at your own risk.
Notice:
- Only SoftEther server is officially supported.
- This app uses VpnService class to establish SSTP connections.
False positive detections:
I tested this app's apk on VirusTotal and confirmed nothing detected as of 2022-11-18. I think I made this app as secure as I can by publishing its source, but it seems that some anti-virus softwares are still warning about this app. I'm sorry to say I cannot handle all false positive detections alone. Your available options may be,
1. Ignore the alert.
2. Submit a false positive report to your anti-virus software's vendor.
3. Build this app from its source.
4. Try another SSTP client.
I hope you will achieve secure communication in some way.
