Buka kunci dengan AES - GCM menggunakan Cloud HSM CLI

Gunakan key unwrap aes-gcm perintah di Cloud HSM CLI untuk membuka kunci payload ke dalam cluster menggunakan kunci pembungkus dan mekanisme AES unwrapping. AES-GCM

Kunci yang tidak dibungkus dapat digunakan dengan cara yang sama seperti kunci yang dihasilkan oleh AWS CloudHSM. Untuk menunjukkan bahwa mereka tidak dihasilkan secara lokal, local atribut mereka disetel kefalse.

Untuk menggunakan key unwrap aes-gcm perintah, Anda harus memiliki kunci AES pembungkus di AWS CloudHSM cluster Anda, dan unwrap atributnya harus disetel ketrue.

Sintaks

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
      --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
  -h, --help
          Print help
