I’ve been studying the well-known “SIGNAL MESSAGING PROTOCOL”,
Its brilliantly designed and completely safe , however I doubt on its implementations
Well-known messenger companies like Whatsapp and Sign declare to have carried out the
e2e messaging protocol for message privateness , however the place are the non-public keys (of customers)
I’m just about certain that the non-public key is not saved within the consumer’s gadget as a result of ,
I drained sending a couple of messages from gadget “A”, switched it off, put in the identical
app in one other gadget “B” and logged in with the identical account. If the non-public key had been saved in gadget “A” then , I have to not be capable to learn the messages from gadget “B” which I had despatched by means of gadget “A” , however I used to be capable of !!
So its fairly apparent that the non-public keys too are saved within the app’s cloud.
If the messaging service supplier too had entry to the non-public key , then they might learn any kinds of knowledge transferred between me and the receiver by means of the app.
And whatsapp claims the next of their sign protocol implementation
Are their claims true?
Simply Curious.. I’m newbie, please right me if my interpretation is unsuitable
