Re-encrypts the data encryption keys that encrypt the object and its chunks. By default, when you create a bucket, the Object Storage service manages the master encryption key used to encrypt each object’s data encryption keys. The encryption mechanism that you specify for the bucket applies to the objects it contains.

You can alternatively employ one of these encryption strategies for an object:

  • You can assign a key that you created and control through the Oracle Cloud Infrastructure Vault service.

  • You can encrypt an object using your own encryption key. The key you supply is known as a customer-provided encryption key (SSE-C).


oci os object reencrypt [OPTIONS]

Required Parameters

--bucket-name, -bn [text]

The name of the bucket. Avoid entering confidential information. Example: my-new-bucket1

--object-name, -on, --name [text]

The name of the object. Avoid entering confidential information. Example: test/object1.log

Optional Parameters

--encryption-key-file [filename]

A file containing the base64-encoded string of the AES-256 encryption key associated with the object.

--from-json [text]

Provide input to this command as a JSON document from a file using the file://path-to/file syntax.

The --generate-full-command-json-input option can be used to generate a sample json file to be used with this command option. The key names are pre-populated and match the command option names (converted to camelCase format, e.g. compartment-id –> compartmentId), while the values of the keys need to be populated by the user before using the sample file as an input to this command. For any command option that accepts multiple values, the value of the key can be a JSON array.

Options can still be provided on the command line. If an option exists in both the JSON document and the command line then the command line specified value will be used.

For examples on usage of this option, please see our “using CLI with advanced JSON options” link:

--kms-key-id [text]

The OCID of the master encryption key used to call the Vault service to re-encrypt the data encryption keys associated with the object and its chunks. If the kmsKeyId value is empty, whether null or an empty string, the API will perform re-encryption by using the kmsKeyId associated with the bucket or the master encryption key managed by Oracle, depending on the bucket encryption mechanism.

--namespace-name, --namespace, -ns [text]

The Object Storage namespace used for the request. If not provided, this parameter will be obtained internally using a call to ‘oci os ns get’

--source-encryption-key-file [filename]

A file containing the base64-encoded string of the AES-256 encryption key associated with the source object.

--version-id [text]

VersionId used to identify a particular version of the object

Example using required parameter

Copy the following CLI commands into a file named Run the command by typing “bash” and replacing the example parameters with your own.

Please note this sample will only work in the POSIX-compliant bash-like shell. You need to set up the OCI configuration and appropriate security policies before trying the examples.

    export bucket_name=<substitute-value-of-bucket_name> #
    export object_name=<substitute-value-of-object_name> #

    oci os object reencrypt --bucket-name $bucket_name --object-name $object_name
