Default Master Key

A Default Master Key is automatically created by another cloud service using KMS, such as Object Storage Service (OBS). The alias of a Default Master Key ends with /default.

You can use the management console to query the status of Default Master Keys, but cannot disable or schedule the deletion of Default Master Keys.

**Table 1** Default Master Keys
Alias	Cloud Service
obs/default	OBS
evs/default	Elastic Volume Service (EVS)
ims/default	Image Management Service (IMS)
sfs/default	Scalable File Service (SFS)

A Default Master Key is automatically created when a user employs the KMS encryption function for the first time in another cloud service.
