Overview

Note:

When passing GenerateDataKeyPairRequest as input to an Aws::Client method, you can use a vanilla Hash:

{
  encryption_context: {
    "EncryptionContextKey" => "EncryptionContextValue",
  },
  key_id: "KeyIdType", # required
  key_pair_spec: "RSA_2048", # required, accepts RSA_2048, RSA_3072, RSA_4096, ECC_NIST_P256, ECC_NIST_P384, ECC_NIST_P521, ECC_SECG_P256K1
  grant_tokens: ["GrantTokenType"],
}

Instance Attribute Details

#encryption_context ⇒ Hash<String,String>

Specifies the encryption context that will be used when encrypting the private key in the data key pair.

An encryption context is a collection of non-secret key-value pairs that represents additional authenticated data. When you use an encryption context to encrypt data, you must specify the same (an exact case-sensitive match) encryption context to decrypt the data. An encryption context is optional when encrypting with a symmetric CMK, but it is highly recommended.

For more information, see Encryption Context in the AWS Key Management Service Developer Guide.

Returns:

  • (Hash<String,String>) —

    Specifies the encryption context that will be used when encrypting the private key in the data key pair.

#grant_tokens ⇒ Array<String>

A list of grant tokens.

For more information, see Grant Tokens in the AWS Key Management Service Developer Guide.

Returns:

  • (Array<String>) —

    A list of grant tokens.

#key_id ⇒ String

Specifies the symmetric CMK that encrypts the private key in the data key pair. You cannot specify an asymmetric CMK or a CMK in a custom key store. To get the type and origin of your CMK, use the DescribeKey operation.

To specify a CMK, use its key ID, Amazon Resource Name (ARN), alias name, or alias ARN. When using an alias name, prefix it with "alias/". To specify a CMK in a different AWS account, you must use the key ARN or alias ARN.

For example:

  • Key ID: 1234abcd-12ab-34cd-56ef-1234567890ab

  • Key ARN: arn:aws:kms:us-east-2:111122223333:key/1234abcd-12ab-34cd-56ef-1234567890ab

  • Alias name: alias/ExampleAlias

  • Alias ARN: arn:aws:kms:us-east-2:111122223333:alias/ExampleAlias

To get the key ID and key ARN for a CMK, use ListKeys or DescribeKey. To get the alias name and alias ARN, use ListAliases.

Returns:

  • (String) —

    Specifies the symmetric CMK that encrypts the private key in the data key pair.

#key_pair_spec ⇒ String

Determines the type of data key pair that is generated.

The AWS KMS rule that restricts the use of asymmetric RSA CMKs to encrypt and decrypt or to sign and verify (but not both), and the rule that permits you to use ECC CMKs only to sign and verify, are not effective outside of AWS KMS.

Possible values:

  • RSA_2048
  • RSA_3072
  • RSA_4096
  • ECC_NIST_P256
  • ECC_NIST_P384
  • ECC_NIST_P521
  • ECC_SECG_P256K1

Returns:

  • (String) —

    Determines the type of data key pair that is generated.
