|
|
Description: Maximum allowed size of objects in the keystore in bytes,
|
|
represented in ASCII decimal format.
|
|
|
|
This is not necessarily the same as the max size that can be
|
|
written to an update file as writes can contain more than
|
|
object data, you should use the size of the update file for
|
|
that purpose.
