Default first key used in the boot image.
This constant represents a 32-byte encryption key used as the first user key (key1) in the boot
image. The exact purpose of this key is not explicitly defined in the documentation. Similar to
the second key, the first byte of the original key has been replaced with \xAA. This key
might be involved in encryption tasks, such as generating OTA firmware images, but its specific
usage is not clearly documented.
