    Re: Extract Encryption Key

    I seriously doubt that there are any published SDK APIs to retrieve the memory card password or the encryption/decryption keys used for the password or the memory card contents. If it was easy (accessible for any user or developer), what'd be the point of protecting the memory cards in the first place?

    Whatever has been published, is in the SDKs. For Symbian^3, more is available via the Symbian source code, too, of course. However, even the Symbian source code probably won't let you retrieve/get what you want (just how to use/interface to the hardware that does, as probably hardware security is involved).

    (For older Symbian/S60 devices, you might find on the net references to an MMCstore file that was accessible, but without any public documentation as to its structure. That hasn't applied since Symbian 9.0 and Symbian Platform Security.)

    http://en.wikipedia.org/wiki/Encryption

    For how it is done on/for Flash memory cards in for real, you may need to go through whatever info is provided by JEDEC, which is the standardization body that "owns" the related specs nowadays: http://www.jedec.org/
