public class MFC421SignatureImpl
extends MFC40SignatureImpl

Helper class for implementation of a signature card service for MFC 4.21 and compatible. Send APDUs to the card. The methods that send APDUs are synchronized simply to reuse the APDU buffers.

Constructor Detail

MFC421SignatureImpl

public MFC421SignatureImpl(MFCSigCodes codes)
Instantiates a new signature card service implementation.
Parameters:
codes - the command codes for the MFC card to support
Method Detail

assertSignDataAlgorithm

public void assertSignDataAlgorithm(java.lang.String alg)
                             throws CardServiceInabilityException
Assert that a specific signature service implementation supports a signature algorithm. The MFC 4.21 card only supports "SHA-1/RSA" and "DSA" (which combines SHA-1 and RawDSA)
Parameters:
alg - The standard algorithm name.
Throws:
CardServiceInabilityException - Thrown if the algorithm is not supported.
Overrides:
assertSignDataAlgorithm in class MFC40SignatureImpl

assertSignHashAlgorithm

public void assertSignHashAlgorithm(java.lang.String alg)
                             throws CardServiceInabilityException
Assert that a specific signature service implementation supports a signature algorithm. The MFC 4.21 card only supports "RSA" and "RawDSA"
Parameters:
alg - The standard algorithm name.
Throws:
CardServiceInabilityException - Thrown if the algorithm is not supported.
Overrides:
assertSignHashAlgorithm in class MFC40SignatureImpl
