<Message type="note">
`KeyManagerKeyEncrypt` and `KeyManagerKeyDecrypt` are also required for principals that never call Key Manager directly: uploading to and downloading from an Object Storage bucket encrypted with [SSE-KMS](/object-storage/how-to/enable-sse-kms/) requires these permissions in addition to the relevant Object Storage permission sets.

Object Storage permission sets alone are not sufficient to read and write objects encrypted with SSE-KMS. An [application](/iam/concepts/#application) that has `ObjectStorageFullAccess` and no Key Manager permission set receives an "access denied" error when it calls `PutObject` on a bucket that has default encryption enabled, even when the KEK and the bucket are in the same Project.
