create_alias(alias_name)
create_alias(alias_name, params::Dict{String,<:Any})

Creates an alias, or a friendly name, for an Amazon Web Services Payment Cryptography key. You can use an alias to identify a key in the console and when you call cryptographic operations such as EncryptData or DecryptData. You can associate the alias with any key in the same Amazon Web Services Region. Each alias is associated with only one key at a time, but a key can have multiple aliases. You can't create an alias without a key. The alias must be unique in the account and Amazon Web Services Region, but you can create another alias with the same name in a different Amazon Web Services Region. To change the key that's associated with the alias, call UpdateAlias. To delete the alias, call DeleteAlias. These operations don't affect the underlying key. To get the alias that you created, call ListAliases. Cross-account use: This operation can't be used across different Amazon Web Services accounts. Related operations: DeleteAlias GetAlias ListAliases UpdateAlias

Arguments

• alias_name: A friendly name that you can use to refer to a key. An alias must begin with alias/ followed by a name, for example alias/ExampleAlias. It can contain only alphanumeric characters, forward slashes (/), underscores (_), and dashes (-). Don't include personal, confidential or sensitive information in this field. This field may be displayed in plaintext in CloudTrail logs and other output.

Optional Parameters

Optional parameters can be passed as a params::Dict{String,<:Any}. Valid keys are:

• "KeyArn": The KeyARN of the key to associate with the alias.

create_key(exportable, key_attributes)
create_key(exportable, key_attributes, params::Dict{String,<:Any})

Creates an Amazon Web Services Payment Cryptography key, a logical representation of a cryptographic key, that is unique in your account and Amazon Web Services Region. You use keys for cryptographic functions such as encryption and decryption. In addition to the key material used in cryptographic operations, an Amazon Web Services 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: SYMMETRICKEY), key algorithm (example: TDES2KEY), key usage (example: TR31P0PINENCRYPTIONKEY) and key modes of use (example: Encrypt). For information about valid combinations of key attributes, see Understanding key attributes in the Amazon Web Services Payment Cryptography User Guide. The mutable data contained within a key includes usage timestamp and key deletion timestamp and can be modified after creation. Amazon Web Services Payment Cryptography binds key attributes to keys using key blocks when you store or export them. Amazon Web Services 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 Amazon Web Services accounts. Related operations: DeleteKey GetKey ListKeys

Arguments

• exportable: Specifies whether the key is exportable from the service.
• key_attributes: 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.

Optional Parameters

Optional parameters can be passed as a params::Dict{String,<:Any}. Valid keys are:

• "Enabled": 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.
• "KeyCheckValueAlgorithm": 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.
• "Tags": Assigns one or more tags to the Amazon Web Services Payment Cryptography key. Use this parameter to tag a key when it is created. To tag an existing Amazon Web Services 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 Amazon Web Services 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 CloudTrail logs and other output. Tagging or untagging an Amazon Web Services Payment Cryptography key can allow or deny permission to the key.

delete_alias(alias_name)
delete_alias(alias_name, params::Dict{String,<:Any})

Deletes the alias, but doesn't affect the underlying key. Each key can have multiple aliases. To get the aliases of all keys, use the UpdateAlias operation. To change the alias of a key, first use DeleteAlias to delete the current alias and then use CreateAlias to create a new alias. To associate an existing alias with a different key, call UpdateAlias. Cross-account use: This operation can't be used across different Amazon Web Services accounts. Related operations: CreateAlias GetAlias ListAliases UpdateAlias

Arguments

• alias_name: A friendly name that you can use to refer Amazon Web Services Payment Cryptography key. This value must begin with alias/ followed by a name, such as alias/ExampleAlias.

delete_key(key_identifier)
delete_key(key_identifier, params::Dict{String,<:Any})

Deletes the key material and metadata associated with Amazon Web Services Payment Cryptography key. Key deletion is irreversible. After a key is deleted, you can't perform cryptographic operations using the key. For example, you can't decrypt data that was encrypted by a deleted Amazon Web Services Payment Cryptography key, and the data may become unrecoverable. Because key deletion is destructive, Amazon Web Services Payment Cryptography has a safety mechanism to prevent accidental deletion of a key. When you call this operation, Amazon Web Services Payment Cryptography disables the specified key but doesn't delete it until after a waiting period set using DeleteKeyInDays. The default waiting period is 7 days. During the waiting period, the KeyState is DELETEPENDING. After the key is deleted, the KeyState is DELETECOMPLETE. You should delete a key only when you are sure that you don't need to use it anymore and no other parties are utilizing this key. If you aren't sure, consider deactivating it instead by calling StopKeyUsage. Cross-account use: This operation can't be used across different Amazon Web Services accounts. Related operations: RestoreKey StartKeyUsage StopKeyUsage

Arguments

• key_identifier: The KeyARN of the key that is scheduled for deletion.

Optional Parameters

Optional parameters can be passed as a params::Dict{String,<:Any}. Valid keys are:

• "DeleteKeyInDays": The waiting period for key deletion. The default value is seven days.

export_key(export_key_identifier, key_material)
export_key(export_key_identifier, key_material, params::Dict{String,<:Any})

Exports a key from Amazon Web Services Payment Cryptography. Amazon Web Services Payment Cryptography simplifies key exchange by replacing the existing paper-based approach with a modern electronic approach. With ExportKey you can export symmetric keys using either symmetric and asymmetric key exchange mechanisms. Using this operation, you can share your Amazon Web Services Payment Cryptography generated keys with other service partners to perform cryptographic operations outside of Amazon Web Services Payment Cryptography For symmetric key exchange, Amazon Web Services Payment Cryptography uses the ANSI X9 TR-31 norm in accordance with PCI PIN guidelines. And for asymmetric key exchange, Amazon Web Services Payment Cryptography supports ANSI X9 TR-34 norm and RSA wrap and unwrap key exchange mechanism. Asymmetric key exchange methods are typically used to establish bi-directional trust between the two parties exhanging keys and are used for initial key exchange such as Key Encryption Key (KEK). After which you can export working keys using symmetric method to perform various cryptographic operations within Amazon Web Services Payment Cryptography. The TR-34 norm is intended for exchanging 3DES keys only and keys are imported in a WrappedKeyBlock format. Key attributes (such as KeyUsage, KeyAlgorithm, KeyModesOfUse, Exportability) are contained within the key block. With RSA wrap and unwrap, you can exchange both 3DES and AES-128 keys. The keys are imported in a WrappedKeyCryptogram format and you will need to specify the key attributes during import. You can also use ExportKey functionality to generate and export an IPEK (Initial Pin Encryption Key) from Amazon Web Services Payment Cryptography using either TR-31 or TR-34 export key exchange. IPEK is generated from BDK (Base Derivation Key) and ExportDukptInitialKey attribute KSN (KeySerialNumber). The generated IPEK does not persist within Amazon Web Services Payment Cryptography and has to be re-generated each time during export. For key exchange using TR-31 or TR-34 key blocks, you can also export optional blocks within the key block header which contain additional attribute information about the key. The KeyVersion within KeyBlockHeaders indicates the version of the key within the key block. Furthermore, KeyExportability within KeyBlockHeaders can be used to further restrict exportability of the key after export from Amazon Web Services Payment Cryptography. The OptionalBlocks contain the additional data related to the key. For information on data type that can be included within optional blocks, refer to ASC X9.143-2022. Data included in key block headers is signed but transmitted in clear text. Sensitive or confidential information should not be included in optional blocks. Refer to ASC X9.143-2022 standard for information on allowed data type. To export initial keys (KEK) or IPEK using TR-34 Using this operation, you can export initial key using TR-34 asymmetric key exchange. You can only export KEK generated within Amazon Web Services Payment Cryptography. 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 Device (KRD). During key export process, KDH is Amazon Web Services Payment Cryptography which initiates key export and KRD is the user receiving the key. To initiate TR-34 key export, the KRD must obtain an export token by calling GetParametersForExport. This operation also generates a key pair for the purpose of key export, signs the key and returns back the signing public key certificate (also known as KDH signing certificate) and root certificate chain. The KDH uses the private key to sign the the export payload and the signing public key certificate is provided to KRD to verify the signature. The KRD can import the root certificate into its Hardware Security Module (HSM), as required. The export token and the associated KDH signing certificate expires after 7 days. Next the KRD generates a key pair for the the purpose of encrypting the KDH key and provides the public key cerificate (also known as KRD wrapping certificate) back to KDH. The KRD will also import the root cerificate chain into Amazon Web Services Payment Cryptography by calling ImportKey for RootCertificatePublicKey. The KDH, Amazon Web Services Payment Cryptography, will use the KRD wrapping cerificate to encrypt (wrap) the key under export and signs it with signing private key to generate a TR-34 WrappedKeyBlock. For more information on TR-34 key export, see section Exporting symmetric keys in the Amazon Web Services Payment Cryptography User Guide. Set the following parameters: ExportAttributes: Specify export attributes in case of IPEK export. This parameter is optional for KEK export. ExportKeyIdentifier: The KeyARN of the KEK or BDK (in case of IPEK) under export. KeyMaterial: Use Tr34KeyBlock parameters. CertificateAuthorityPublicKeyIdentifier: The KeyARN of the certificate chain that signed the KRD wrapping key certificate. ExportToken: Obtained from KDH by calling GetParametersForImport. WrappingKeyCertificate: The public key certificate in PEM format (base64 encoded) of the KRD wrapping key Amazon Web Services Payment Cryptography uses for encryption of the TR-34 export payload. This certificate must be signed by the root certificate (CertificateAuthorityPublicKeyIdentifier) imported into Amazon Web Services Payment Cryptography. When this operation is successful, Amazon Web Services Payment Cryptography returns the KEK or IPEK as a TR-34 WrappedKeyBlock. To export initial keys (KEK) or IPEK using RSA Wrap and Unwrap Using this operation, you can export initial key using asymmetric RSA wrap and unwrap key exchange method. To initiate export, generate an asymmetric key pair on the receiving HSM and obtain the public key certificate in PEM format (base64 encoded) for the purpose of wrapping and the root certifiate chain. Import the root certificate into Amazon Web Services Payment Cryptography by calling ImportKey for RootCertificatePublicKey. Next call ExportKey and set the following parameters: CertificateAuthorityPublicKeyIdentifier: The KeyARN of the certificate chain that signed wrapping key certificate. KeyMaterial: Set to KeyCryptogram. WrappingKeyCertificate: The public key certificate in PEM format (base64 encoded) obtained by the receiving HSM and signed by the root certificate (CertificateAuthorityPublicKeyIdentifier) imported into Amazon Web Services Payment Cryptography. The receiving HSM uses its private key component to unwrap the WrappedKeyCryptogram. When this operation is successful, Amazon Web Services Payment Cryptography returns the WrappedKeyCryptogram. To export working keys or IPEK using TR-31 Using this operation, you can export working keys or IPEK using TR-31 symmetric key exchange. In TR-31, you must use an initial key such as KEK to encrypt or wrap the key under export. To establish a KEK, you can use CreateKey or ImportKey. Set the following parameters: ExportAttributes: Specify export attributes in case of IPEK export. This parameter is optional for KEK export. ExportKeyIdentifier: The KeyARN of the KEK or BDK (in case of IPEK) under export. KeyMaterial: Use Tr31KeyBlock parameters.
