Signal is a free and open-source encrypted messaging and voice calling application for iOS, Android and desktop computers. The software was developed by Open Whisper Systems, a non-profit organization based in the United States. The application uses end-to-end encryption to secure all communications to other Signal users.
The best messaging encryption
One of the key features of Signal is its end-to-end encryption, which ensures that only the intended recipients can read the messages. The encryption is applied automatically and seamlessly, without any input or action required from the user.
The encryption keys are generated and stored on the user’s device, rather than on a central server, ensuring that only the intended recipients have access to the messages. In addition to text messaging, Signal also supports voice and video calls, as well as the ability to send images, videos and other files.
The calls are also encrypted end-to-end, ensuring that only the intended recipients can hear the conversation. Signal also features a “disappearing messages” feature, which allows users to set a timer for messages to automatically delete after a certain period of time.
Privacy and Security in higher level
Another important feature of Signal is its focus on privacy and security. The application does not collect or store any metadata about its users’ communications and it does not include any third-party tracking or advertising.
In addition, Signal’s source code is open-source, allowing experts to review and verify the security of the software. Signal is available for download on the official website of the software.
The application is compatible with Windows, MacOS, Linux and can be installed on a desktop computer or laptop. It is also available for mobile devices, including iOS and Android. The app can be downloaded from the Apple App Store and Google Play store.
Signal for Desktop
The Signal app for desktop computers includes all of the same features as the mobile version, including end-to-end encryption, voice and video calls and the ability to send images, videos and other files.
The desktop version also includes a feature called “Linked Devices”, which allows users to link their mobile devices with their desktop computers, so that they can seamlessly switch between devices while still maintaining their conversations.
Overall, Signal is a powerful and secure communication tool that is designed with privacy and security in mind. It offers a wide range of features, including end-to-end encryption, voice and video calls and the ability to send images, videos and other files.
The application is open-source and does not collect or store any metadata about its users’ communications. Signal is available for free on the official website and can be installed on a desktop computer or laptop running Windows, MacOS, or Linux, as well as mobile devices running iOS and Android.
