Encryption of files on an external MicroSD card on a Passport

I have recently purchased a 200g MicroSD Card that I want to backup a bunch of my Photos on My PASSPORT onto (Passport has a 128g MicroSD card installed) I was hoping to copy my files from the phone to the new MicroSD card connected to the passport via USB port.

While that is easy enough to do I was wondering if there was some way to encript the files or password protect the folders on the external MicroSD card so that should someone access the SD card at some point my files would be protected from being viewed?

Any suggestions would be appreciated.

Thanks for the info but this provides me only with the ability to encrypt the media on an MicroSD card installed in a BlackBerry I was looking for an option to encrypt the info transferred to an external SD card via the Micro USB port?

Lots of ways to encrypt an SD Card used with a PC or Mac.

But then it will be unusable in the BlackBerry.

Yep... was hoping for a solution that would work with BlackBerry

You're not going to really find a reliable method that your handset and another device are going to both be able to read.

You can try an app named mega. Its basically a cloud storage app but gets ya work done. Yu can select a particular folder to encrypt in ya sd card.
