[S2] Keys are generated by passing the SHA256 hash as the KeySource to the relevant [[SPL_services|spl:ldn]] command with the above Generation, with the full hash being passed to the Ounce cmds. Only the first 0x10-bytes of the output key is used, since AES-128 is used even with Ounce. | [S2] Keys are generated by passing the SHA256 hash as the KeySource to the relevant [[SPL_services|spl:ldn]] command with the above Generation, with the full hash being passed to the Ounce cmds.
