The dev.kp file is encrypted with ES block encryption, and the contents of an example dev.kp file after decryption is shown below.
Note that the console id itself is burned in an OTP area of the TWL CPU, and changing the contents of this file will not actually change the console id.
This file contains the unique per-console ECC private-public key pair, along with a certificate issued by Nintendo.
