 ** ExportDukptInitialKey **   <a name="paymentcryptography-Type-ExportAttributes-ExportDukptInitialKey"></a>
Parameter information for IPEK export.  
Type: [ExportDukptInitialKey](API_ExportDukptInitialKey.md) object  
Required: No

 ** KeyCheckValueAlgorithm **   <a name="paymentcryptography-Type-ExportAttributes-KeyCheckValueAlgorithm"></a>
The algorithm that AWS Payment Cryptography uses to calculate the key check value (KCV). It is used to validate the key integrity. Specify KCV for IPEK export only.  
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 | HMAC | SHA_1`   
Required: No
