decryptData
Decrypts ciphertext data to plaintext using symmetric, asymmetric, or DUKPT data encryption key. For more information, see Decrypt data in the Amazon Web Services Payment Cryptography User Guide.
You can use an encryption key generated within Amazon Web Services Payment Cryptography, or you can import your own encryption key by calling ImportKey. For this operation, the key must have KeyModesOfUse set to Decrypt. In asymmetric decryption, Amazon Web Services Payment Cryptography decrypts the ciphertext using the private component of the asymmetric encryption key pair. For data encryption outside of Amazon Web Services Payment Cryptography, you can export the public component of the asymmetric key pair by calling GetPublicCertificate.
For symmetric and DUKPT decryption, Amazon Web Services Payment Cryptography supports TDES and AES algorithms. For asymmetric decryption, Amazon Web Services Payment Cryptography supports RSA. When you use DUKPT, for TDES algorithm, the ciphertext data length must be a multiple of 16 bytes. For AES algorithm, the ciphertext data length must be a multiple of 32 bytes.
For information about valid keys for this operation, see Understanding key attributes and Key types for specific data operations in the Amazon Web Services Payment Cryptography User Guide.
