I'm convinced in 10 years nobody owns a personal computer anymore. But a smartphone. - Bruno Zuber, 2012

* Our apps on Android 2.3.3/4.0.3 run with newest OpenSSL 1.0.2l / zlib 1.2.11 and can be updated immediately when new security bugs arrive. Standard Android 2.3.3 built in security for apps uses outdated/unsecure OpenSSL 1.0.0a, Android 4.0.3 OpenSSL 1.0.0e / zlib 1.2.5. Without our security solution Android apps communicate unsecure. Bring security under YOUR control. Don't hope that producers of Android smartphones bring security to your app and your customer.
