Perhaps just blocking it with a white box and then converting it into an image-only pdf. This makes the file much bigger but will keep the exact same layout while also removing the text blocked by the white box.
Or does it have any interactive elements? What do you mean by "layers"?
Dude ever heard of a double edged sword? As I already stated, requiring a phone number HAS downsides but it also has upsides.
There will be more spam and scam accounts to worry about on Signal than on SimpleX, I can almost guarantee it! At least if simpleX gets more popular of course.But yes, no phone number does indeed increase anonymity, but not so much privacy.
I view Signal as the bridge between absolute non-techies and me, so they can at least navigate and use the app, while I am not sacrificing too much privacy.
And I use simpleX with other people who are more tech inclined.
Alright I think I know what you mean, but I'm still not sure we're actually on the same page regarding encryption.
If a company is forced to do whatever ths government commands it to do, that's only valid within certain constraints.
For example, the company cannot be forced to grow wings snd fly to thr heavens. That's physically impossible.
Similarly, it also cannot provide the decrypted messages of its users because it (like Signal) does not have the KEYS that are absolutely 100% necessary for decrypting the encrypted messages of its users.
So, again, it's physically impossible to hand over either the keys or the decrypted messages.
However, there is one remedy that Signal CAN do, if somehow forced. That's changing the Signal program. It certainly can push an update that sends Signal the keys for decryption.
However, at that point, the source code at github doesn't match the compiled binary of the program anymore, and very good chance people would notice, and thereby people would lose trust in Signal.
I'm not sure about the examples you gave about the government being successful in obtaining user details of a company. Were those details encrypted as well? Was the source code publically available? Was the program popular?
Do you understand what encryption means? Genuine question.
If a company is compelled to spy on its users, it doesn't mean hack them. (although perhaps there are same edge cases where you have to wonder the exact definition of hacking)
What if you have randomized MAC address for wifi? Will that solve it completely ?
