How easy is to decompile the kernel and find those custom encrypting functions?
HOW TO CHANGE CID SD CARD MANUAL
It might be better to use a pre-made encrypted bootloader (like TrueCrypt or LUKS, which both work on the Raspberry Pi) and avoid having to make any manual kernel modifications.
HOW TO CHANGE CID SD CARD GENERATOR
This would make it easier to brute-force the password, especially if one is just emulating an SD card after cloning yours (which is something else you might want to consider).įinally, using any kind of pseudo-random number generator already has some intrinsic flaws, precisely because it's not random - there is a reason it's called pseudo-random. Some people have even demonstrated the ability to overwrite the CID with certain SD cards. The CID of an SD card is only supposed to be read-only, but it's not uncommon to find non-compliant flash memory devices in this day and age. Without a doubt, using a predefined CID as a password, as well as using a custom pseudo-random number generation function. How hard it is to 'break' your setup depends on the number of bits of entropy in whatever method you're using to sign/encrypt the filesystem itself (as this determines the total number of unique combinations that can be used to brute-force the password). How easy it would be to break this setup (to decrypt the root filesystem and make it boot from any sd card)?

Initrd will try to mount the filesystem using that generated password. (a hash function is used, did not decide yet over md5 or sha1). The initrd generates the filesystems' password according to the CID of the SD card.The approach uses an initrd to mount an encrypted root filesystem.China 8GB 16GB Change CID SD Card IOKZ077-#7124 is supplied by ☆ 8GB 16GB Change CID SD Card manufacturers, producers, suppliers on Global. The CID number is a unique card identifier number that is unique to the card itself.
HOW TO CHANGE CID SD CARD SOFTWARE
Most phones and much of the software on phones will lock in to the CID number of a SD card.
HOW TO CHANGE CID SD CARD SERIAL NUMBER
Some also call this “reading the PSN off the SD card” or reading the product serial number off the SD card. The following snippet works on my droid (TI omap based platform) but not on Qualcomm MSM based platforms.I am trying to copy-protect some work, which is a bootable SD card booting a Linux kernel on ARM device (Raspberry Pi). It is possible to read out the cid value from the linux /sys file system if you know your platform. To provide some background the SD card is connected to a hw-controller that is specific to the device platform.

HOW TO CHANGE CID SD CARD ANDROID
There is no Android API that can do this that I am aware of and for a general solution that is needed.
