Re: [Blink] [SIP Beyond VoIP] New Blink for Mac beta version with OpenPGP support

[Adrian Georgescu]

The keys are tied to the sip account used inside the app, the uuid is for 
example for sip:a...@sip2sip.info

The app generates these keys on the fly as they do not yet exists anywhere. 
Also one can replicate these keys among devices to make sure one can read them 
on all devices.

If, when using the same identity as one’s email, for example then you would 
want to reuse an existing key, maybe?

Considering the I start the client, I have a SIP account and want to talk to 
someone lets say  leena...@example.com 

I believe that is fine if I can retrieve the key prior to start a chat. But 
what is the benefit as at the destination one needs a compatible client as well 
and the moment you start it, it will generate a new key and exchange it 
automatically with the other end-point. So the user need not be aware about 
this key exchange, as knowing about it would introduce complexity (manage the 
key manually)

So I am struggling with understanding the possible benefits of importing and 
exporting these keys in to an end-to-end delivery system that takes care 
automatically about this complexity.

 THis sounds great. Do you have more information on the implementation. Is 
 it only MESSAGE or SIP messages in general? Have you implemented PGP key 
 lookup somehow?

Hi Olle,

I have a question for you.

Given that the keys can be used only inside the app, so one must have the app 
to make sue of the keys, and the app automatically manages these keys and 
exchange them, what would be the benefit of a lookup function in a public 
repository for keys?

Regards,
Adrian

Only SIP Message.

We have not implement key lookup but it could be easily added, I suppose..

THis sounds great. Do you have more information on the implementation. Is it 
only MESSAGE or SIP messages in general? Have you implemented PGP key lookup 
somehow?

Very curious.

As always, thank you for your work!
