[Dev] [Android] [Encryption] Encrypting/ decrypting the SD card from the application
Hi team, For a research me and my team is building an application to secure corporate data and we are using the SD card as the storage. We are trying to encrypt the SD card when exiting the application and decrypt when accessing the application. I tried to search a way to encrypt the SD card but couldn't find any hints. Please help if anyone of you have any idea on this Thank you and best regards -- *Tharindu Athukorala* Contact me: Mobile: +94710848793 Email: tharindu.athukor...@aiesec.net Skype: tharindu.athukorala ___ Dev mailing list Dev@wso2.org http://wso2.org/cgi-bin/mailman/listinfo/dev

Re: [Dev] [EMM]
Hi Milan, Thank you soo much for the reply. In our application we are trying find a solution for COPE (Corporate Owned Personally Enabled) devices. We thought to use SD cards and use that SD card to store corporate data and encrypt that SD card. Is there any possibility to do that using the android encryption ?

Hi all, I'm Tharindu from SLIIT an undergraduate of cyber security. I'm trying to encrypt and decrypt files from the SD card using AES 256 in android for the research work. In WSO2 EMM system you have used a wrapper concept and can anyone tell me how this wrapper concept works and what is the encryption mechanism you have used ?
