Scartare una chiave CLOUDHSM-AES-GCM usando Cloud HSM CLI

Usa il key unwrap cloudhsm-aes-gcm comando in Cloud HSM CLI per estrarre una chiave di payload nel AWS CloudHSM cluster usando la chiave di wrapping e il meccanismo di unwrapping. AES CLOUDHSM-AES-GCM

Le chiavi non impacchettate possono essere utilizzate nello stesso modo delle chiavi generate da. AWS CloudHSM Per indicare che non sono state generate localmente, il loro local attributo è impostato su. false

Per utilizzare il key unwrap cloudhsm-aes-gcm comando, è necessario disporre della chiave di AES wrapping nel AWS CloudHSM cluster e il relativo unwrap attributo deve essere impostato su. true

Sintassi

aws-cloudhsm > help key unwrap cloudhsm-aes-gcm
Usage: key unwrap cloudhsm-aes-gcm [OPTIONS] --filter [<FILTER>...] --tag-length-bits <TAG_LENGTH_BITS> --key-type-class <KEY_TYPE_CLASS> --label <LABEL> <--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
      --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
  -h, --help
          Print help
