Why an Authorized Account or User Cannot Upload or Download KMS Encrypted Objects?

Before using the server-side encryption function of OBS, ensure that the KMS Administrator permission has been granted to the account or user on IAM. If the current account or user is the grantee, it also requires the KMS Administrator permission. Contact your entrusting party for authorization. For details, see Account Delegation.

Note: Data Encryption Workshop (DEW), to which KMS is a sub-service, is not available globally. Therefore, the KMS Administrator permission must be configured in the region where the bucket resides. The agency information is stored on IAM. The configuration takes effect approximately 15 minutes after the configuration is complete.
