Although the keydata is presumably common to all consoles, each keyblob is console-unique, because the key used to encrypt it is at the factory is console unique. Each keyblob has its own encryption key, with keyblob key N generated by decrypting keyblob key seed N with the SBK, and keyblob key seed N generated by decrypting keyblob N's seed constant with the device keyblob seed generation key obtained from the Falcon. Keyblob key 1 is special: In addition to being used to decrypt keyblob 1, it is also used to generate the master device key by decrypting a constant block. | Although the keydata is presumably common to all consoles, each keyblob is console-unique, because the key used to encrypt it is at the factory is console unique.
