Here are some of them: Use of phone numbers The controversies emanate from the implementation of the Signal protocol on the Signal messaging app. In fact, it is the gold standard in which other messaging apps implement: WhatsApp, Skype, Google’s RCS and even Facebook Messenger. The Signal protocol is the cryptography behind the Signal messaging app. You can think of cryptography as the theory and implementation as the practice.
Another way to look at this is the difference between theory and practice. Implementation is the application of cryptography in the form of computer programming code. Is Signal still safe?įirst, you need to understand the line between cryptography and implementation. However, some of their decisions were controversial. The encryption keys are stored on users' phones and computers, never on servers, and to avoid the potential risk (albeit a very small one) of spoofing, you'll be warned if the security key of anyone you are talking with changes.Signal has the reputation of being the most private messaging app. Signal also allows users to choose how long messages and conversations are available for, meaning you can create self-destructing messages that are rendered completely inaccessible – by anyone – after a period of your choosing. The app says it keeps messages secure using end-to-end encryption using its own Signal Protocol, which means no one other than the sender and the intended recipient is able to see messages. Signal is available for Windows, macOS, Linux (Debian-based distros), iOS and Android, and offers mobile and desktop versions. Signal has seen user numbers soar in recent months as customers look for a more secure way to message and stay in touch.
