  KeyUsage: String

Properties

KeyAlgorithm

The key algorithm to be use during creation of an AWS Payment Cryptography key.

For symmetric keys, AWS Payment Cryptography supports AES and TDES algorithms. For asymmetric keys, AWS Payment Cryptography supports RSA and ECC_NIST algorithms.

Required: Yes

Type: String

Allowed values: TDES_2KEY | TDES_3KEY | AES_128 | AES_192 | AES_256 | RSA_2048 | RSA_3072 | RSA_4096

Update requires: No interruption

KeyClass

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

Required: Yes

Type: String

Allowed values: SYMMETRIC_KEY | ASYMMETRIC_KEY_PAIR | PRIVATE_KEY | PUBLIC_KEY

Update requires: No interruption

KeyModesOfUse

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

Required: Yes

Type: KeyModesOfUse

Update requires: No interruption

KeyUsage

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

Required: Yes

Type: String

Allowed values: TR31_B0_BASE_DERIVATION_KEY | TR31_C0_CARD_VERIFICATION_KEY | TR31_D0_SYMMETRIC_DATA_ENCRYPTION_KEY | TR31_D1_ASYMMETRIC_KEY_FOR_DATA_ENCRYPTION | TR31_E0_EMV_MKEY_APP_CRYPTOGRAMS | TR31_E1_EMV_MKEY_CONFIDENTIALITY | TR31_E2_EMV_MKEY_INTEGRITY | TR31_E4_EMV_MKEY_DYNAMIC_NUMBERS | TR31_E5_EMV_MKEY_CARD_PERSONALIZATION | TR31_E6_EMV_MKEY_OTHER | TR31_K0_KEY_ENCRYPTION_KEY | TR31_K1_KEY_BLOCK_PROTECTION_KEY | TR31_K3_ASYMMETRIC_KEY_FOR_KEY_AGREEMENT | TR31_M3_ISO_9797_3_MAC_KEY | TR31_M1_ISO_9797_1_MAC_KEY | TR31_M6_ISO_9797_5_CMAC_KEY | TR31_M7_HMAC_KEY | TR31_P0_PIN_ENCRYPTION_KEY | TR31_P1_PIN_GENERATION_KEY | TR31_S0_ASYMMETRIC_KEY_FOR_DIGITAL_SIGNATURE | TR31_V1_IBM3624_PIN_VERIFICATION_KEY | TR31_V2_VISA_PIN_VERIFICATION_KEY | TR31_K2_TR34_ASYMMETRIC_KEY
