It was never allowed. Microsoft just started doing it in their email client and obnoxiously made it default. There was no standards process where anyone spent time considering the …

>Neither mode is encrypted: whatever is on the sending screen is readable by any camera pointed at it. Something like this would be good for transferring the public key(s) associat…

GPS is direct sequence spread spectrum. You might be thinking of frequency hopping, jamming that is harder, but you are only working against super weak signals from satellites. It …

A rehash of the paywalled Wired article: * https://futurism.com/science-energy/us-military-gps-jamming-...

The point of the comic is pretty obviously to make fun of the expectations of cryptography geeks; you know, the sort of people who use 4096 bit RSA keys for the coolness factor. It…

To avoid a potential misunderstanding, the maintenance mode is intended to continue indefinitely. Briar project is not shutting down. * https://briarproject.org/news/2026-maintenan…

>...and conductive, rivaling copper. That isn't true for either thermal or electrical conductivity. So I don't know what is meant here.

But claiming that your system is end to end encrypted means that you are claiming protection from you and your system. This is mainly a truth in advertising issue.

>...pretty much any E2E system is falling under this definition. The definition is quite clear. It does not apply when the implementation is not distributed by the same entity that…

If, say, Signal was completely controlled by the CIA[1] and was thus evil, then having incoherent cryptography as described in the article would be a feature, not a bug. Being able…

How about GPG distributed with a Linux distribution like Debian as a counterexample? It would be fairly difficult to backdoor GPG in that case without getting caught. Everything ha…

>SpaceX plans to send one million more satellites into orbit, for space-based data centres, ... I think we should wait to see how the first satellite data centre works out. It seem…

The linked article makes the argument that looking at the BSD licensed example code in the RFC that defines Opus would mean that code written based on that understanding would be a…

A signature is not authentication in itself. It is only such if the signing entity is in some way restricting what it is willing to sign. The domain part of the email address in th…

The article makes a reference to the failed ARC (Authenticated Received Chain) proposal which was intended to help DKIM not break email forwarding: https://www.ietf.org/archive/id/…

>Anyone can put anything in the “From” field of an email. ... and then the article goes on to talk about SPF, DKIM and DMARC which authenticates only the domain part of the "From" …

If you specifically mean something that can embody Shor's algorithm, it is fairly clear these days that a fundamental breakthrough is required. So the timeline extends from tomorro…

Deliverability issues with which email provider(s)? Often times it turns out the problem is just with Gmail.

Gmail is one of the shoddiest of the ultra-cheap email providers. If you use Gmail, a significant number of messages will disappear. They don't go to junk, they just disappear. Gma…

I guess there is an interesting possibility here. Perhaps the targets were encrypting end to end (that is more or less the default now with XMPP clients). With the TLS over top of …

>That technology overlaps only partially, at best, with what’s used in quantum processors. Dunno, how can you say that for sure when we don't actually know how to make a practical …

6x10 here. Even more text. Only readable because each pixel is completely distinct.

A cryptographic identity is a public key as used in a public key signature scheme. So a particular person is represented by a ridiculously long number. That number can be shortened…

From the article: >IBM is developing four custom ASICs — a decoder, a two-qubit gate controller, a single-qubit controller, and an amplifier — designed to handle quantum control at…
