Default second key used in the application subimage.
This constant represents a 32-byte encryption key, which is used as the second user key (key2)
in the application subimage. The key is defined here as a default, though its exact purpose
is not explicitly documented. It is worth noting that the first byte of the original key has
been replaced with \xBB. This key may be used during OTA firmware image generation or
other encryption tasks where a second key is required.
