You're talking about encryption and signal because you're worried about folks whose network you're connected to being able to invade your privacy, right?
LOL no? I'd never blow the whistle on my employer from my desk. Even if I did, I would connect to a different network.
I recognize other people are not as conscious as I am of that vulnerability but you asked about me, specifically.
If you don't worry about those guys, who do have access to traffic info, then why bother with encryption?
Any number of other people. Primarily the government.

Right, so if the header isn't encrypted, it'd be trivial for them to see who you're sending to, which is why that's important.
You never answered my question - do you think the network connection itself is encrypted? Or just the content of the messages?
-
No they can't.
E: if someone wants to provide evidence to the contrary instead of just downvoting and moving on, please, go ahead.
Here's a relevant stack exchange question.
Regarding what an ISP can learn. Of note, everybody is ceding that the ISP can tell you're using signal, and they've moved on to whether or not they'd be able to fingerprint your usage patterns. -
100,000 people check the news, one person is whistleblowing.
There are many many more people using Signal to yell at their kids to do the dishes or some shit. Not whistleblowing.
Thats a big red arrow pointing to only people sending encrypted messages.
Everyone is using encrypted messages...
I'm sorry you can't grasp this concept. I guess study a different subject.

The Guardian launches Secure Messaging, a world-first from a media organisation, in collaboration with the University of Cambridge
Secure Messaging is a new innovation for confidential story-sharing and source protection, underpinning the Guardian’s commitment to investigative journalism.
The Guardian has published the open source code for this important tech to enable adoption by other media organisations.the Guardian (www.theguardian.com)
If you want to blow the whistle on somebody and wonder if the Guardian is trustworthy I suggest you ask Julian Assange.

I don't know everything. Just because it's not explicitly listed today doesn't mean it won't be tomorrow. This was just created yesterday. And it does the same thing that all of those listed apps do: facilitates private communication.
Yeah but contrary to these listed, the judge know the guardian is a newspaper, they shouldn't be able to make him/her afraid in the same way they did.

Technical summary: it seems OK against an observer who can see the network traffic but hasn't infiltrated the phone of the source or the computer of the news organization.
Any real message is stored locally on the smartphone by the CoverDrop module and sent as the next CoverDrop message, i.e. replacing the dummy message which would otherwise have been sent. Consequently a network observer cannot determine whether any communication is taking place and CoverDrop therefore provides the potential source with plausible deniability.
The CoverNode and each journalist has their own public-private key pair. These keys are published by the news organization and available to the CoverDrop module directly so the user does not need know about them. When the CoverDrop module is used for the first time, it generates a new, random public-private key pair
for the user.All real CoverDrop messages sent by the CoverDrop module to the CoverNode include the text written by the potential source as well as their own public key. The message is first encrypted using the public key of the journalist who will ultimately receive the message, then encrypted a second time using the public key of the CoverNode. All dummy CoverDrop messages are encrypted using the public key of the CoverNode. All messages, real or dummy, are arranged to be the same, fixed length. Encryption and length constraints ensure that only the CoverNode can distinguish between real and dummy messages.

To sum it up even more : this looks like standard end-to-end encryption, but any app user have the same network traffic, completed with fake data if no communication is needed.

The logic does not check out. Signal isn't going to integrate a news section and then suddenly be exempt from this regulation.

It show you didn't read, I am explaining the article piece by piece. They used the lost a gave you to convince a judge it was a terrorist behavior. It is not forbidden to crypt things. And they would not have been able to convince a judge the news application guardian is a terrorist tool.
And I am bad a English so I am trying to resume a English article to you in broken English. I am sure I use the wrong word and as long as you don't read you can keep playing me. You are taking more time debating things I have an hard time explain than reading the article.
Do you wan me to copy paste in entirely here so you can avoid one click ? -

And they would not have been able to convince a judge the news application guardian is a terrorist tool.
I think it's pretty obvious that they could.
