[--cli-input-json <value>]
[--generate-cli-skeleton <value>]
[--debug]
[--endpoint-url <value>]
[--no-verify-ssl]

[--cli-read-timeout <value>]
[--cli-connect-timeout <value>]

Options¶

--key-identifier (string)

The KeyARN of the Amazon Web Services Payment Cryptography key.

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI 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.

--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. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

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. If automatic pagination is disabled, the AWS CLI will only make one call, for the first page of results.

--output (string)

The formatting style for command output.

json
text
table

--query (string)

A JMESPath query to use in filtering the response data.

--profile (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
auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

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.

Examples¶

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal's quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

To get the metadata of a key

The following get-key example returns the metadata of the key associated with the alias. This operation does not return cryptographic material.

aws payment-cryptography get-key \
    --key-identifier alias/sampleAlias1

Output¶

Key -> (structure)

The key material, including the immutable and mutable data for the key.

KeyArn -> (string)

The Amazon Resource Name (ARN) of the key.

KeyAttributes -> (structure)

The role of the key, the algorithm it supports, and the cryptographic operations allowed with the key. This data is immutable after the key is created.

KeyUsage -> (string)

The cryptographic usage of an Amazon Web Services Payment Cryptography key as deﬁned in section A.5.2 of the TR-31 spec.

KeyClass -> (string)

The type of Amazon Web Services Payment Cryptography key to create, which determines the classiﬁcation of the cryptographic method and whether Amazon Web Services Payment Cryptography key contains a symmetric key or an asymmetric key pair.

KeyAlgorithm -> (string)

The key algorithm to be use during creation of an Amazon Web Services Payment Cryptography key.

For symmetric keys, Amazon Web Services Payment Cryptography supports AES and TDES algorithms. For asymmetric keys, Amazon Web Services Payment Cryptography supports RSA and ECC_NIST algorithms.

KeyModesOfUse -> (structure)

The list of cryptographic operations that you can perform using the key.

Encrypt -> (boolean)

The algorithm that Amazon Web Services Payment Cryptography uses to calculate the key check value (KCV). It is used to validate the key integrity.

For TDES keys, the KCV is computed by encrypting 8 bytes, each with value of zero, with the key to be checked and retaining the 3 highest order bytes of the encrypted result. For AES keys, the KCV is computed using a CMAC algorithm where the input data is 16 bytes of zero and retaining the 3 highest order bytes of the encrypted result.
