Overview

Scenario

Tags are the identifier of DEW. Adding tag allows you to easily recognize and manage your data encryption resources.

Tag Naming Rules

• Each tag consists of a key-value pair.
• You can add at most 20 tags to a DEW resource.
• For each resource, a tag key must be unique and can have only one tag value.
• A tag consists of a tag key and a tag value. The naming rules are listed in Table 1.
• Tags are key-value pairs, which are used to identify, classify, and search for vaults. Vault tags are used to filter and manage vaults only. A vault can have up to 10 tags.
  

  If you have configured tag policies for DEW, add tags for keys and secrets based on the policies. If the tag does not comply with the policies, keys and secrets may fail to be created. Contact the administrator to learn more about tag policies.
