import-key

Description

Imports keys and public key certificates into Amazon Web Services Payment Cryptography.

Amazon Web Services Payment Cryptography simplifies main or root key exchange process by eliminating the need of a paper-based key exchange process. It takes a modern and secure approach based of the ANSI X9 TR-34 key exchange standard.

You can use ImportKey to import main or root keys such as KEK (Key Encryption Key) using asymmetric key exchange technique following the ANSI X9 TR-34 standard. The ANSI X9 TR-34 standard uses asymmetric keys to establishes bi-directional trust between the two parties exchanging keys.

After you have imported a main or root key, you can import working keys to perform various cryptographic operations within Amazon Web Services Payment Cryptography using the ANSI X9 TR-31 symmetric key exchange standard as mandated by PCI PIN.

You can also import a root public key certificate , a self-signed certificate used to sign other public key certificates, or a trusted public key certificate under an already established root public key certificate.

To import a public root key certificate

Using this operation, you can import the public component (in PEM cerificate format) of your private root key. You can use the imported public root key certificate for digital signatures, for example signing wrapping key or signing key in TR-34, within your Amazon Web Services Payment Cryptography account.

Set the following parameters:

  • KeyMaterial : RootCertificatePublicKey
  • KeyClass : PUBLIC_KEY
  • KeyModesOfUse : Verify
  • KeyUsage : TR31_S0_ASYMMETRIC_KEY_FOR_DIGITAL_SIGNATURE
  • PublicKeyCertificate : The certificate authority used to sign the root public key certificate.
To import a trusted public key certificate

The root public key certificate must be in place and operational before you import a trusted public key certificate. Set the following parameters:

  • KeyMaterial : TrustedCertificatePublicKey
  • CertificateAuthorityPublicKeyIdentifier : KeyArn of the RootCertificatePublicKey .
  • KeyModesOfUse and KeyUsage : Corresponding to the cryptographic operations such as wrap, sign, or encrypt that you will allow the trusted public key certificate to perform.
  • PublicKeyCertificate : The certificate authority used to sign the trusted public key certificate.
Import main keys

Amazon Web Services Payment Cryptography uses TR-34 asymmetric key exchange standard to import main keys such as KEK. In TR-34 terminology, the sending party of the key is called Key Distribution Host (KDH) and the receiving party of the key is called Key Receiving Host (KRH). During the key import process, KDH is the user who initiates the key import and KRH is Amazon Web Services Payment Cryptography who receives the key. Before initiating TR-34 key import, you must obtain an import token by calling GetParametersForImport . This operation also returns the wrapping key certificate that KDH uses wrap key under import to generate a TR-34 wrapped key block. The import token expires after 7 days.

Set the following parameters:

  • CertificateAuthorityPublicKeyIdentifier : The KeyArn of the certificate chain that will sign the signing key certificate and should exist within Amazon Web Services Payment Cryptography before initiating TR-34 key import. If it does not exist, you can import it by calling by calling ImportKey for RootCertificatePublicKey .
  • ImportToken : Obtained from KRH by calling GetParametersForImport .
  • WrappedKeyBlock : The TR-34 wrapped key block from KDH. It contains the KDH key under import, wrapped with KRH provided wrapping key certificate and signed by the KDH private signing key. This TR-34 key block is generated by the KDH Hardware Security Module (HSM) outside of Amazon Web Services Payment Cryptography.
  • SigningKeyCertificate : The public component of the private key that signed the KDH TR-34 wrapped key block. In PEM certificate format.

Note

TR-34 is intended primarily to exchange 3DES keys. Your ability to export AES-128 and larger AES keys may be dependent on your source system.

Import working keys

Amazon Web Services Payment Cryptography uses TR-31 symmetric key exchange standard to import working keys. A KEK must be established within Amazon Web Services Payment Cryptography by using TR-34 key import. To initiate a TR-31 key import, set the following parameters:

  • WrappedKeyBlock : The key under import and encrypted using KEK. The TR-31 key block generated by your HSM outside of Amazon Web Services Payment Cryptography.
  • WrappingKeyIdentifier : The KeyArn of the KEK that Amazon Web Services Payment Cryptography uses to decrypt or unwrap the key under import.

Cross-account use: This operation can’t be used across different Amazon Web Services accounts.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command’s default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination.

--output (string)

The formatting style for command output.

  • json
  • text
  • table
  • yaml
  • yaml-stream

--query (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

  • on
  • off

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

--cli-binary-format (string)

The formatting style to be used for binary blobs. The default format is base64. The base64 format expects binary blobs to be provided as a base64 encoded string. The raw-in-base64-out format preserves compatibility with AWS CLI V1 behavior and binary values must be passed literally. When providing contents from a file that map to a binary blob fileb:// will always be treated as binary and use the file contents directly regardless of the cli-binary-format setting. When using file:// the file contents will need to properly formatted for the configured cli-binary-format.

  • base64
  • raw-in-base64-out

--no-cli-pager (boolean)

Disable cli pager for output.
