Desencapsular uma chave com o AES-GCM usando a CLI do CloudHSM

Use o comando key unwrap aes-gcm na CLI do CloudHSM para desencapsular uma chave de carga útil no cluster usando a chave de encapsulamento AES e o mecanismo de desencapsulamento AES-GCM.

As chaves desembrulhadas podem ser usadas da mesma forma que as chaves geradas pelo AWS CloudHSM. Para indicar que elas não foram geradas localmente, o atributo local é definido como false.

Para usar o key unwrap aes-gcm comando, você deve ter a chave de encapsulamento AES em seu AWS CloudHSM cluster e seu unwrap atributo deve estar definido como. true

Sintaxe

aws-cloudhsm > help key unwrap aes-gcm
Usage: key unwrap aes-gcm [OPTIONS] --filter [<FILTER>...] --tag-length-bits <TAG_LENGTH_BITS> --key-type-class <KEY_TYPE_CLASS> --label <LABEL> --iv <IV> <--data-path <DATA_PATH>|--data <DATA>>

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
      --filter [<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 key to unwrap with
      --data-path <DATA_PATH>
          Path to the binary file containing the wrapped key data
      --data <DATA>
          Base64 encoded wrapped key data
      --attributes [<UNWRAPPED_KEY_ATTRIBUTES>...]
          Space separated list of key attributes in the form of KEY_ATTRIBUTE_NAME=KEY_ATTRIBUTE_VALUE for the unwrapped key
      --share-crypto-users [<SHARE_CRYPTO_USERS;...]
          Space separated list of Crypto User usernames to share the unwrapped key with
      --manage-key-quorum-value <MANAGE_KEY_QUORUM_VALUE;
          The quorum value for key management operations for the unwrapped key
      --use-key-quorum-value <USE_KEY_QUORUM_VALUE;
          The quorum value for key usage operations for the unwrapped key
      --aad <AAD>
          Aes GCM Additional Authenticated Data (AAD) value, in hex
      --tag-length-bits <TAG_LENGTH_BITS>
          Aes GCM tag length in bits
      --key-type-class <KEY_TYPE_CLASS>
          Key type and class of wrapped key [possible values: aes, des3, ec-private, generic-secret, rsa-private]
      --label <LABEL>
          Label for the unwrapped key
      --session
          Creates a session key that exists only in the current session. The key cannot be recovered after the session ends
      --iv <IV>
          Initial value used to wrap the key, in hex
      --approval <APPROVAL>
          Filepath of signed quorum token file to approve operation
  -h, --help
          Print help
