You discover that your application is receiving an HTTP 4xx error when reading the object from Cloud Storage. What is a possible cause of this error?
A
You attempted the read operation on the object with the customer's base64-encoded key.
17%
B
You attempted the read operation without the base64-encoded SHA256 hash of the encryption key.

// explanation
When reading objects encrypted with customer-supplied encryption keys (CSEK), Cloud Storage requires both the base64-encoded AES-256 key and the base64-encoded SHA256 hash of that key. Omitting the required key hash causes the API request to fail with a 4xx client error.
