Android encrypted app package

asec files are specially encrypted Android app packages that are used to move apps between the device main storage and the SD card.


Further details

Files with asec extension are encrypted app packages used in the Google Android operating system. It is a file format used to install encrypted applications.

ASEC file format was launched with Android 2.2, enabling the transfer of applications to an SD card installed in an Android phone. Applications stored on the SD Card are protected by ASEC encryption to prevent modification and corruption.

When an app is downloaded from the Android Market, it is placed in a .asec file in a secure area of the storage device. This prevents the app from being modified or tampered with. The .asec file also includes a digital signature that can be used to verify the integrity of the app.

ASEC encrypted applications can only be executed on the Android phone where they were installed, or in an Android SDK emulator. If an application is moved back from the SD card to the phone's local storage, Android decrypts the ASEC application file into a standard APK application package.
