All the needed keys are located in (with libgourou) .adept directory :
* devicesalt for local encryption
* activation.xml that contains encrypted RSA public/private keys

devicesalt helps to decrypt RSA keys, that are then used to retrieve AES key used for ePub encryption.

Key generation is partially done locally (devicesalt + unencrypted RSA) and remotely (encrypted RSA).

libgourou manage key generation & server exchange in order to build all these files with right data.

For your question :
