// Decrypts ciphertext data to plaintext using symmetric, asymmetric, or DUKPT
// data encryption key. For more information, see Decrypt data (https://docs.aws.amazon.com/payment-cryptography/latest/userguide/decrypt-data.html)
// 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 (https://docs.aws.amazon.com/payment-cryptography/latest/APIReference/API_ImportKey.html)
// . 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 (https://docs.aws.amazon.com/payment-cryptography/latest/APIReference/API_GetPublicKeyCertificate.html)
// . 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 (https://docs.aws.amazon.com/payment-cryptography/latest/userguide/keys-validattributes.html)
// and Key types for specific data operations (https://docs.aws.amazon.com/payment-cryptography/latest/userguide/crypto-ops-validkeys-ops.html)
