CreateKey - AWS Payment Cryptography Control Plane


Creates an AWS Payment Cryptography key, a logical representation of a cryptographic key, that is unique in your account and AWS Region. You use keys for cryptographic functions such as encryption and decryption.

In addition to the key material used in cryptographic operations, an AWS Payment Cryptography key includes metadata such as the key ARN, key usage, key origin, creation date, description, and key state.

When you create a key, you specify both immutable and mutable data about the key. The immutable data contains key attributes that define the scope and cryptographic operations that you can perform using the key, for example key class (example: SYMMETRIC_KEY), key algorithm (example: TDES_2KEY), key usage (example: TR31_P0_PIN_ENCRYPTION_KEY) and key modes of use (example: Encrypt). For information about valid combinations of key attributes, see Understanding key attributes in the AWS Payment Cryptography User Guide. The mutable data contained within a key includes usage timestamp and key deletion timestamp and can be modified after creation.

AWS Payment Cryptography binds key attributes to keys using key blocks when you store or export them. AWS Payment Cryptography stores the key contents wrapped and never stores or transmits them in the clear.

Cross-account use: This operation can't be used across different AWS accounts.

Request Syntax

{ "Enabled": boolean, "Exportable": boolean, "KeyAttributes": { "KeyAlgorithm": "string", "KeyClass": "string", "KeyModesOfUse": { "Decrypt": boolean, "DeriveKey": boolean, "Encrypt": boolean, "Generate": boolean, "NoRestrictions": boolean, "Sign": boolean, "Unwrap": boolean, "Verify": boolean, "Wrap": boolean }, "KeyUsage": "string" }, "KeyCheckValueAlgorithm": "string", "Tags": [ { "Key": "string", "Value": "string" } ] }

Request Parameters

The request accepts the following data in JSON format.


Specifies whether to enable the key. If the key is enabled, it is activated for use within the service. If the key is not enabled, then it is created but not activated. The default value is enabled.

Type: Boolean

Required: No


Specifies whether the key is exportable from the service.

Type: Boolean

Required: Yes


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.

Type: KeyAttributes object

Required: Yes


The algorithm that AWS 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.

Type: String

Valid Values: CMAC | ANSI_X9_24

Required: No


Assigns one or more tags to the AWS Payment Cryptography key. Use this parameter to tag a key when it is created. To tag an existing AWS Payment Cryptography key, use the TagResource operation.

Each tag consists of a tag key and a tag value. Both the tag key and the tag value are required, but the tag value can be an empty (null) string. You can't have more than one tag on an AWS Payment Cryptography key with the same tag key.


Don't include personal, confidential or sensitive information in this field. This field may be displayed in plaintext in AWS CloudTrail logs and other output.


Tagging or untagging an AWS Payment Cryptography key can allow or deny permission to the key.

Type: Array of Tag objects

Array Members: Minimum number of 0 items. Maximum number of 200 items.

Required: No
