When installing a CIA, the encrypted title key is decrypted by the 3DS, with the common key. The title key itself is encrypted in the ticket of the CIA. NOTE: When the CXI packaged into a CIA it is encrypted again with a title key(Using AES-CBC). The 3DS holds the AccessDesc public key, which is used to verify the NCCH RSA pubk, which is used to verify the header which contains hashes for all of the NCCH components. But essentially, this provides the chain of trust. This prevents developers from creating applications with special permissions. The AccessDesc is signed with the AccessDesc RSA-2048 private key. The AccessDesc contains the public key used to verify the NCCH signature, as well as a mirror of the permissions in the Extended header. *Technical Note: All RSA keypairs which developers are given to use, come with a pre-generated AccessDesc.

The encryption key can be either:ģ/ Dynamically Generated Key (Unique per NCCH) Developer NCCH files can be (and are usually) encrypted. CCI is the file extention ) or a CIA (installable title). Then the NCCH files are then packaged into a NCSD container (this is the format for game cartridge images, usually. All games/applications ( NCCH format) made for panda dev units must be signed, this is done by signing (with the private key from a RSA-2048 keypair*) a SHA-256 hash which was generated over the NCCH header.
