Sending keys to Ursula #248

Closed dominic-healid closed 4 years ago

dominic-healid commented 5 years ago

Has anyonce can provide sample code for the re-encryption process where Ursulas are involved like sending keys to them and receiving it?

I believe on the sample code it only simulate the logic for sending the receiving fragments from the ursula nodes. 

When Alice wants to grant Bob access to open her encrypted messages, she creates re-encryption key fragments, or "kfrags", which are next sent to N proxies or Ursulas.

How do we send the kfrags to Ursulas?

Upon analyzing it more, I believe Ursulas are part of NuCypher network and this pyUmbral sample code is independent to NuCypher that's why sending the keys to Ursulas are not specified.

That's what I think also. Thus to send kfrags to Ursulas without using NuCypher, you should implement it yourself.
