Built packages available on bintray are now signed, which is very good !.. but where can I find the public key for the verification of these signatures ??
Thanks a lot !
Any feedback on this question ? 
Thanks!
This is indeed missing documentation on our end.
The packages are currently signed using Bintray’s key.
You can get the public key at:
