Estrarre una chiave con RSA-AES utilizzando la CLI di CloudhSM

Utilizzate il key unwrap rsa-aes comando nella CLI di CloudHSM per decomprimere una chiave di payload utilizzando una chiave privata RSA e il meccanismo di unwrapping. RSA-AES

Le chiavi decomposte 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 ilkey unwrap rsa-aes, è necessario disporre della chiave privata RSA della chiave di wrapping pubblica RSA nel AWS CloudHSM cluster e il relativo unwrap attributo deve essere impostato su. true

Tipo di utente

I seguenti tipi di utenti possono eseguire questo comando.

Sintassi

aws-cloudhsm > help key unwrap rsa-aes
Usage: key unwrap rsa-aes [OPTIONS] --filter [<FILTER>...] --hash-function <HASH_FUNCTION> --mgf <MGF> --key-type-class <KEY_TYPE_CLASS> --label <LABEL> <--data-path <DATA_PATH>|--data <DATA>>

Options:
      --cluster-id <CLUSTER_ID>

      --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
      --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]
      --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
      --approval <APPROVAL>
          Filepath of signed quorum token file to approve operation
  -h, --help
          Print help
