Wrap a key with AES-ZERO-PAD using CloudHSM CLI

Use the key wrap aes-zero-pad command in CloudHSM CLI to wrap a payload key using an AES key on the hardware security module HSM) and the AES-ZERO-PAD 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 aes-zero-pad command, you must first have an AES key in your AWS CloudHSM cluster. You can generate an AES key for wrapping using the Generate a symmetric AES key with CloudHSM CLI command with the wrap attribute set to true.

User type

The following types of users can run this command.

Requirements

Syntax

aws-cloudhsm > help key wrap aes-zero-pad
Usage: key wrap aes-zero-pad [OPTIONS] --payload-filter [<PAYLOAD_FILTER>...] --wrapping-filter [<WRAPPING_FILTER>...]

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
  -h, --help
          Print help

Example

This example shows how to use the key wrap aes-zero-pad command using an AES key with the wrap attribute value set to true.

aws-cloudhsm > key wrap aes-zero-pad --payload-filter attr.label=payload-key --wrapping-filter attr.label=aes-example
{
  "error_code": 0,
  "data": {
    "payload_key_reference": "0x00000000001c08f1",
    "wrapping_key_reference": "0x00000000001c08ea",
    "wrapped_key_data": "L1wVlL/YeBNVAw6Mpk3owFJZXBzDLONt"
  }
}
