License:

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.
