<p>A messaging app that self-destructs all text, video, and picture messages for privacy purposes now comes with features that make finding friends and sharing media easierbut still ultra-privately.</p><p>Wickr, a startup co-founded by DefCon veteran and security venture catalyst Nico Sell, in June released the free app for the iPhone that comes with anti-forensics features so messages can't be resurrected. The app ensures that there's no trace of online communication to avoid access by governments, corporations, or cybercriminals.</p><p>Sell points out that one of Wickr's key uses is anonymous correspondence between journalists and their sources that can't be intercepted or traced. The app is based on 256-bit symmetric AES encryption and RSA 4096 encryption, as well as a proprietary algorithm, and Wickr's servers have no view of user accounts: they only store a cryptographic version of the user IDs and hardware IDs.</p><p>Wickr now works across all iOS devices to a user's account, and can send among Wickr users secure and self-destructing PDFs and images from Dropbox, Box, and Google Drive.</p><p><a href="http://www.darkreading.com/mobile-security/167901113/security/privacy/240147606/military-grade-ios-secure-messaging-app-gets-user-friendlier.html">Keep reading...</a></p>
