“Photos from the past, meet scanner from the future.” Actually does what it says on the tin. Also simplifies the task of taking pictures of documents greatly.
“We need to remember that we’re fighting not only against government surveillance, but also against corporate surveillance as well. We need ways to defend against this, and using corporate solutions that create a dependency on these solutions, even if the communications themselves are not readable to them, there’s still the issue of metadata, and of course general availability of Google’s services to Signal.” Sander Venema disagrees on strategy, not cryptography.
“While all three apps use the same secure-messaging protocol, they differ on exactly what information is encrypted, what metadata is collected, and what, precisely, is stored in the cloud—and therefore available, in theory at least, to government snoops and wily hackers.” Bottom line: Micah Lee recommends that you use Signal by Open Whisper Systems whenever you can.
“Already 20 smartphones and laptops are ours. If he wanted to, Slotboom is now able to completely ruin the lives of the people connected.” Wouter Slotboom is one of the good guys, demonstrating to Maurits Martijn his effortless ability to retrieve people’s passwords, steal their identity, and plunder their bank accounts.
“I am regularly impressed with the thought and care put into both the security and the usability of this app. It’s my first choice for an encrypted conversation.”
Signal offers private messaging and calling in one simple app. It is both free and open source. Development is supported by community donations and grants. This means that there are no hidden strings attached. Use Signal as an alternative to WhatsApp or, better still, its replacement.
“Hackers can’t steal your stuff and annoying advertisers can’t track you. Connect to any hotspot, public or private without exposing your traffic. Access geo-restricted content by changing your virtual location. Control your privacy and security at the push of a button.”
“Threema is a mobile messaging app that puts security first. With true end-to-end encryption, you can rest assured that only you and the intended recipient can read your messages.” Threema is my favourite instant messaging application and has been described as “a much flasher version of WhatsApp”. Its source code has recently undergone an external security audit and was found to provide a ”security level which compares favourably with the state of the art in similar messaging services“.
