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) 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.
