Wrap a key with RSA-OAEP using CloudHSM CLI

Use the key wrap rsa-oaep command in CloudHSM CLI to wrap a payload key using an RSA public key on the hardware security module (HSM) and the RSA-OAEP wrapping mechanism. The payload key’s extractable attribute must be set to true.

Only the owner of a key, that is the crypto user (CU) who created the key, can wrap the key. Users who share the key can use the key in cryptographic operations.

To use the key wrap rsa-oaep command, you must first have an RSA key in your AWS CloudHSM cluster. You can generate an RSA key pair using the The generate-asymmetric-pair category in CloudHSM CLI command and the wrap attribute set to true.

User type

The following types of users can run this command.

Syntax

aws-cloudhsm > help key wrap rsa-oaep
Usage: key wrap rsa-oaep [OPTIONS] --payload-filter [<PAYLOAD_FILTER>...] --wrapping-filter [<WRAPPING_FILTER>...] --hash-function <HASH_FUNCTION> --mgf <MGF>

Options:
      --cluster-id <CLUSTER_ID>
          Unique Id to choose which of the clusters in the config file to run the operation against. If not provided, will fall back to the value provided when interactive mode was started, or error
      --payload-filter [<PAYLOAD_FILTER>...]
          Key reference (e.g. key-reference=0xabc) or space separated list of key attributes in the form of attr.KEY_ATTRIBUTE_NAME=KEY_ATTRIBUTE_VALUE to select a payload key
      --wrapping-filter [<WRAPPING_FILTER>...]
          Key reference (e.g. key-reference=0xabc) or space separated list of key attributes in the form of attr.KEY_ATTRIBUTE_NAME=KEY_ATTRIBUTE_VALUE to select a wrapping key
      --path <PATH>
          Path to the binary file where the wrapped key data will be saved
      --wrapping-approval <WRAPPING_APPROVALR>
          File path of signed quorum token file to approve operation for wrapping key
      --payload-approval <PAYLOAD_APPROVALR>
          File path of signed quorum token file to approve operation for payload key
      --hash-function <HASH_FUNCTION>
          Hash algorithm [possible values: sha1, sha224, sha256, sha384, sha512]
      --mgf <MGF>
          Mask Generation Function algorithm [possible values: mgf1-sha1, mgf1-sha224, mgf1-sha256, mgf1-sha384, mgf1-sha512]
  -h, --help
          Print help

Example

This example shows how to use the key wrap rsa-oaep command using an RSA public key with the wrap attribute value set to true.

aws-cloudhsm > key wrap rsa-oaep --payload-filter attr.label=payload-key --wrapping-filter attr.label=rsa-public-key-example --hash-function sha256 --mgf mgf1-sha256
{
  "error_code": 0,
  "data": {
    "payload-key-reference": "0x00000000001c08f1",
    "wrapping-key-reference": "0x00000000007008da",
    "wrapped-key-data": "OjJe4msobPLz9TuSAdULEu17T5rMDWtSlLyBSkLbaZnYzzpdrhsbGLbwZJCtB/jGkDNdB4qyTAOQwEpggGf6v+Yx6JcesNeKKNU8XZal/YBoHC8noTGUSDI2qr+u2tDc84NPv6d+F2KOONXsSxMhmxzzNG/gzTVIJhOuy/B1yHjGP4mOXoDZf5+7f5M1CjxBmz4Vva/wrWHGCSG0yOaWblEvOiHAIt3UBdyKmU+/My4xjfJv7WGGu3DFUUIZ06TihRtKQhUYU1M9u6NPf9riJJfHsk6QCuSZ9yWThDT9as6i7e3htnyDhIhGWaoK8JU855cN/YNKAUqkNpC4FPL3iw=="
