AWSKMSGetParametersForImportRequest

Objective-C

@interface AWSKMSGetParametersForImportRequest

Swift

class AWSKMSGetParametersForImportRequest

  • The identifier of the KMS key that will be associated with the imported key material. The Origin of the KMS key must be EXTERNAL.

    All KMS key types are supported, including multi-Region keys. However, you cannot import key material into a KMS key in a custom key store.

    Specify the key ID or key ARN of the KMS key.

    For example:

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

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

    To get the key ID and key ARN for a KMS key, use ListKeys or DescribeKey.

    Declaration

    Objective-C

    @property (nonatomic, strong) NSString *_Nullable keyId;

    Swift

    var keyId: String? { get set }

  • The algorithm you will use with the RSA public key (PublicKey) in the response to protect your key material during import. For more information, see Select a wrapping algorithm in the Key Management Service Developer Guide.

    For RSA_AES wrapping algorithms, you encrypt your key material with an AES key that you generate, then encrypt your AES key with the RSA public key from KMS. For RSAES wrapping algorithms, you encrypt your key material directly with the RSA public key from KMS.

    The wrapping algorithms that you can use depend on the type of key material that you are importing. To import an RSA private key, you must use an RSA_AES wrapping algorithm.

    • RSA_AES_KEY_WRAP_SHA_256 — Supported for wrapping RSA and ECC key material.

    • RSA_AES_KEY_WRAP_SHA_1 — Supported for wrapping RSA and ECC key material.

    • RSAES_OAEP_SHA_256 — Supported for all types of key material, except RSA key material (private key).

      You cannot use the RSAES_OAEP_SHA_256 wrapping algorithm with the RSA_2048 wrapping key spec to wrap ECC_NIST_P521 key material.

    • RSAES_OAEP_SHA_1 — Supported for all types of key material, except RSA key material (private key).

      You cannot use the RSAES_OAEP_SHA_1 wrapping algorithm with the RSA_2048 wrapping key spec to wrap ECC_NIST_P521 key material.

    • RSAES_PKCS1_V1_5 (Deprecated) — Supported only for symmetric encryption key material (and only in legacy mode).

    Declaration

    Objective-C

    @property (nonatomic) AWSKMSAlgorithmSpec wrappingAlgorithm;

    Swift

    var wrappingAlgorithm: AWSKMSAlgorithmSpec { get set }

  • The type of RSA public key to return in the response. You will use this wrapping key with the specified wrapping algorithm to protect your key material during import.

    Use the longest RSA wrapping key that is practical.

    You cannot use an RSA_2048 public key to directly wrap an ECC_NIST_P521 private key. Instead, use an RSA_AES wrapping algorithm or choose a longer RSA public key.

    Declaration

    Objective-C

    @property (nonatomic) AWSKMSWrappingKeySpec wrappingKeySpec;

    Swift

    var wrappingKeySpec: AWSKMSWrappingKeySpec { get set }
