Descriptions

Wire is an open source secure messenger. Users of Wire by Bund may bypass the mandatory encryption at rest feature by simply disabling their device passcode. Upon launching, the app will attempt to enable encryption at rest by generating encryption keys via the Secure Enclave, however it will fail silently if no device passcode is set. The user has no indication that encryption at rest is not active since the feature is hidden to them. This issue has been resolved in version 3.70

Wire es una mensajería segura de código abierto. Los usuarios de Wire by Bund pueden omitir la funcionalidad mandatory encryption at rest simplemente deshabilitando el código de acceso de su dispositivo. Al iniciarse, la aplicación intentará habilitar el cifrado en reposo al generar claves de cifrado por medio del Enclave Seguro, pero fallará silenciosamente si no se ha establecido un código de acceso en el dispositivo. El usuario no presenta ninguna indicación de que el cifrado en reposo no está activo, ya que la funcionalidad está oculta para él. Este problema ha sido resuelto en la versión 3.70
