updateMK

Function

Updates all master keys.

Syntax

./kmc_tool all --updateMK

• By default, a maximum number of 4096 keys can be stored in KMC. When updating keys, pay attention to the maximum number.
• After keys are updated, the old keys will not be deleted. If you want to delete the old keys, re-encrypt all the encrypted content, that is, enable the ZooKeeper security feature again.

Example

./kmc_tool all --updateMK

The new ciphertext is stored in the user-defined folder (ensure that you have the write permission on the folder).
