                byte[] cryptogram,
                byte algorithmID)
         throws CardTerminalException,
                CardServiceException

The device decrypts a cryptogram and returns the plain text.

Parameters:

privateKey - the private SmartCardHSMKey

cryptogram -

algorithmID - one of RSA_DECRYPTION_Plain, RSA_DECRYPTION_V15 or RSA_DECRYPTION_OAEP

Returns:

the plain text

Throws:

CardTerminalException

CardServiceException

performECCDH

byte[] performECCDH(SmartCardHSMKey privateKey,
                    byte[] pkComponents)
             throws CardTerminalException,
                    CardServiceException

The device calculates a shared secret point using an EC Diffie-Hellman operation. The public key of the sender must be provided as input to the command. The device returns the resulting point on the curve associated with the private key.

Parameters:

privateKey - Key identifier of the SmartCardHSM private key

pkComponents - Concatenation of '04' || x || y point coordinates of ECC public Key

Returns:

Concatenation of '04' || x || y point coordinates on EC curve

Throws:

CardServiceException

CardTerminalException
