Encrypting SD contents

[PFlores81]

Not sure if anyone has asked this, but how can I implement the encryption library to encrypt specific folders on the SD card ?

I've read through just about every thread about encryption but the only one that comes close is encrypting jpegs with the RAF library.

There is no automatic way to do it. You will need to read each file and then store it again encrypted.

Damn, OK. I could force the android encryption however I need to be able to truly encrypt certain files.
Thanks Erel.

Erel,

Would it be possible for you to give me a brief example on reading a file or copying then encrypting.. it seems everything I've read there is no tutorial or exact reference given.

Thanks again

You can read a file into a bytes array with the code in this post: http://www.b4x.com/forum/basic4andr...10012-writing-image-byte-array.html#post55567

Then there are several options. The simplest one is to use RandomAccessFile.WriteObject and save the bytes array.

Thanks Erel. Ill test it out with a simple small zip file and text doc..
