Are you looking into encrypting individual files? org.bouncycastle.*
have the crypto functions that you can use to encrypt a file.
You might also want to check this policy:
http://developer.android.com/reference/android/app/admin/DeviceAdminInfo.html#USES_ENCRYPTED_STORAGE
which is the best encryption algorithem i can use for?
There are symmetric ones and asymmetric ones. You are likely more
interested in symmetric encryption, where the keys used for encryption
and decryption are the same. DES and ASE are the most popular ones.
